SPSL Technology

Silanna UV Makes Ultraviolet LED Manufacturing Breakthrough With Nanostructures

Easy wavelength tuning, higher power at short wavelengths, and exceptional lifetime performance

Brisbane, Australia, 15 September, 2022 – A major breakthrough in UV-C LED technology from Silanna UV offers huge advantages for applications as diverse as disinfection, water quality monitoring, gas sensing, liquid chromatography, and chemical and biological analysis. The new manufacturing approach promises to make deep ultraviolet and far ultraviolet LEDs easier to make, more efficient at shorter wavelengths, and more reliable. With the renewed focus on air, water and surface disinfection following the Covid-19 pandemic, these next-generation UV LEDs are already attracting interest.

Silanna UV’s groundbreaking patented short period superlattice (SPSL) approach overcomes many of the difficulties that plague competing AlGaN UV-C LED technologies. In essence, Silanna UV has effectively created a new material, a nanostructure, which is much easier to control and has properties that are far superior to traditional AlGaN. The benefits for UV-C LED quality are revolutionary.

Moving beyond traditional UV LEDs

For years, UV-C LED manufacturers have relied on traditional AlGaN Aluminum Gallium Nitride alloy) formulas. In theory, by adjusting the ratio of aluminum and gallium metal in the alloy lattice, the bandgap can be tuned to produce UV emissions from 340 nm to 210 nm, covering most of the UV spectrum. But in reality, emission below 260nm require high Al-content AlGaN, which, unlike GaN, makes it very difficult to achieve desirable n and p-type doping, particularly at the shortest wavelengths, leading to poor electrical performance. High-Al content AlGaN also suffers from light extraction issues due to the polarization of emitted light, causing significant loss of light output, particularly in the far UV range below 240nm

Silanna UV’s breakthrough SPSL material

To overcome these problems in UV LEDs, Silanna UV uses new technology. Instead of the common AlGaN method, Silanna UV uses SPSL.

In this approach, rather than using a crude old-fashioned ternary alloy, alternating layers of AlN and GaN (as many as several hundred layers) are meticulously built up to create a so-called SPSL. Unlike a traditional ternary alloy, this SPSL’s key properties – including bandgap and conductivity – can be finely tuned by simply adjusting the thickness of the constituent layers. This means that the issues caused by High-Al content AlGaN are mitigated – in particular, that older method’s poor electrical characteristics and short wavelength light-loss.

The SPSL technology gives Silanna UV huge advantages over UV-C LED competitors, including the maintenance of high power at shorter wavelengths, superior electrical properties, and outstanding lifetime performance.

Worlds First Anyport

Silanna Semiconductor’s Roll Out of AnyPort™ Architecture Will Dramatically Simplify Development of Multi Port Chargers

By choosing AnyPort architecture designers can quickly configure additional ports to new and existing high-efficiency, fast charger designs

San Diego, CA – May 24th, 2022– Silanna Semiconductor, The Power Density Leader, has announced that it will be making its flexible AnyPort™ architecture for multiport chargers available for a wide variety of silicon- and GaN-based designs supporting power levels beyond 100W.

AnyPort is an innovative new architecture that gives designers the flexibility to complete a charger design for a given power level prior to specifying and configuring the specific number and type of output ports. By allowing a single base charger design to be deployed across a variety of end products with different output configurations, AnyPort can significantly speed the development and reduce the complexity of fast chargers and adapters with multiple Type-C and/or Type-A [four] output ports.

AnyPort brings together Silanna’s CO2 Smart Power™ families of advanced ACF controllers and high-frequency DC/DC converters to deliver high-power-density, ultra-efficient, multi-port charger solutions for USB-PD applications between 30W and 150W. The ability to specify port count and type at the end of the design process is made possible by combining a fixed-output front-end AC/DC stage powered by Silanna Semicondcutor’s ACF controller and multiple downstream DC/DC stages independently regulating any number of Type-C and Type-A ports.

AnyPort was first deployed in Silanna Semiconductor’s RD-5 all-silicon reference design, a production-ready solution that provides everything an engineer needs to rapidly prototype and test a fully functional 65W 2C charger. As well as incorporating AnyPort into future silicon- and GaN-based reference designs, the company is now planning to make the AnyPort architecture available to all customers of its advanced AC/DC and DC/DC technologies.

“By allowing designers to start work on a charger design before deciding on the number and type of outputs AnyPort represents a significant step forward in terms of the design flexibility it offers OEM and aftermarket charger and adapter manufacturers,” says Hubie Noto, Silanna Semiconductor’s director of product marketing. “Basing a design around AnyPort architecture speeds development, minimizes the BoM required across multiple charger models and allows companies to launch and modify high-efficiency, high-power-density products in the shortest possible timescales.”

Silanna’s ultra-high-efficiency ACF controllers integrate into an ultra-compact 16-pin SOIC package an adaptive digital PWM controller, ultra-high-voltage (UHV) active clamp FET, active clamp gate driver and startup regulator and provide the simplicity of a simple flyback controller with all the benefits of an ACF design. This includes recycling the leakage inductance energy of the flyback transformer and limiting the primary FET drain voltage spike during turn-off events. Employing Silanna Semiconductor’s OptiModeTM digital control architecture, these controllers adjust the device’s mode of operation on a cycle-by-cycle basis to maintain high efficiency, low EMI, fast dynamic load regulation, and other key power supply parameters in response to varying line voltage and load conditions.

Supplied in miniature QFN packages, Silanna’s DC-DC portfolio comprises high-voltage, high-efficiency, wide-input integrated buck converters that offer selectable switching frequencies and have unique features to optimize performance in USB port power supply applications. Extremely low operating power dissipation enables very low no-load power – an important specification for regulatory certification – while a momentary internal feedback path allows for clean and well-controlled start-up operation until external USB-PD controllers can bias themselves and take over control of the output voltage.

AnyPort Key Features and Benefits

  • Fully configurable – any number and type of output ports
  • Design is governed by maximum output power only
  • Significantly improves the development speed and reduces the complexity of multi-port fast charger and adapter designs
  • Enabled by Silanna Semiconductor’s end-to-end AC/DC and DC/DC line of products

Bringing together the company’s CO2 Smart Power™ families of advanced ACF controllers and high-frequency DC/DC converters, the new AnyPort™ RD-5 delivers a high-power-density, ultra-efficient, production-ready solution for multi-port 65W USB-PD applications.

Representing the latest addition to Silanna’s growing family of silicon- and GaN-based fast charger reference designs, the RD-5 is an all-silicon solution that will simplify and speed charger development by providing everything an engineer needs to rapidly prototype and test a fully functional 65W 2C unit. The design, which combines Silanna’s SZ1130 fully-integrated AC/DC active clamp flyback (ACF) controller and two of the company’s SZPL3102 DC/DC converters, provides a cased power density of 11.4W/inch3 and operates with an end-to-end peak efficiency in excess of 91.5%. Efficiency is quite flat across the universal input voltage range (90 – 265Vac). Because the design exceeds conducted and radiated EMI requirements by more than 6dB it eliminates the need for pre-production validation and certification, speeding up the production cycle.

“Through its CO2 Smart Power family Silanna offers a range of end-to-end AC/DC and DC/DC technologies that allow designers to develop high-efficiency, high-power-density charging solutions with a low BoM,” says Ahsan Zaman, Silanna Semiconductor’s director of product marketing. “By bringing together these technologies in the RD-5 AnyPort™ reference design we are providing designers with the fastest possible route from prototyping to full production of fast chargers with any number or type of output ports.”

Silanna’s ultra-high-efficiency SZ1130 ACF controller is rated for powers up to 65W in universal input designs and above 100W in PFC applications. The controller integrates into an ultra-compact 16-pin SOIC package an adaptive digital PWM controller, ultra-high-voltage (UHV) active clamp FET, active clamp gate driver and startup regulator and provides the simplicity of a simple flyback controller with all the benefits of an ACF design. This includes recycling the leakage inductance energy of the flyback transformer and limiting the primary FET drain voltage spike during turn-off events. Employing Silanna Semiconductor’s OptiModeTM digital control architecture, the SZ1130 adjusts the device’s mode of operation on a cycle-by-cycle basis to maintain high efficiency, low EMI, fast dynamic load regulation, and other key power supply parameters in response to varying line voltage and load conditions.

Supplied in a tiny 3mm x 3mm QFN package, the SZPL3102 is a high-voltage, high-efficiency 65W integrated buck converter with a selectable switching frequency up to 2MHz. The device offers a wide input range of 7V to 27V, delivers a maximum output current of 3.25A and has unique features to optimize performance in USB port power supply applications. Extremely low operating power dissipation enables very low no-load power – an important specification for regulatory certification – while a momentary internal feedback path allows for clean and well controlled start-up operation until external USB-PD controllers can bias themselves and take over control of the output voltage.

The RD-5 joins a comprehensive family of production-ready reference designs that provide everything needed to develop high-density chargers with low operational and no-load/ stand-by power consumption and minimum component count, BOM cost and size. This family includes all-silicon 33W and 45W solutions and silicon- and GaN-based single-output 65W USB-PD reference designs. Full availability of PCB Gerber and production files further reduces the time from prototyping to full production.

Industry’s most efficient all-silicon Active Clamp Flyback (ACF) 65W design joins 33W silicon and 65W GaN variants to deliver industry’s most comprehensive family of production-ready USB-PD GaN and silicon solutions   

San Diego, CA – 23rd February, 2022 – Silanna Semiconductor, The Power Density Leader, has launched a new active clamp flyback (ACF)-based reference design that simplifies and speeds the development of 65W 1C fast charger applications built using silicon power ICs. Featuring the company’s latest CO2 Smart Power™ ACF controller technology, the Silanna Semiconductor RD-31 provides a route to delivering performance that matches or exceeds that of many commercially available 65W GaN-based chargers at a cost more readily associated with conventional silicon designs.

The RD-31 is the latest in a family of production-ready reference designs that provide everything needed to prototype and develop a fully functional charger with low operational and no-load/ stand-by power consumption and minimum component count, BOM cost and size. This family includes all-silicon 33W and GaN-based 65W USB-PD reference designs.

As with the company’s existing 65W GaN and 33W silicon reference designs, Silanna’s new RD-31 is based on the ultra-high-efficiency SZ1131 ACF controller, which is rated for 65W and above 100W operation in universal input and PFC applications, respectively. This controller offers the industry’s highest level of integration by incorporating an adaptive digital PWM controller, ultra-high-voltage (UHV) active clamp FET, active clamp gate driver and startup regulator into a single compact device.

Providing an (uncased) power density of 30W/inch3, the RD-31 operates with a peak efficiency of around 94% and has a no-load power consumption below 25mW. Efficiency is flat across the universal input voltage range (90 – 265Vac) and the reference design is fully production-ready as it exceeds conducted and radiated EMI requirements by more than 6dB. In benchmarking tests the RD-31 exceeded the efficiency of the best-in-class commercially available GaN-based power adapter by 0.5% and reduced no-load vampire power by as much as 44%.

“We are committed to helping engineers deliver high-performance chargers with ever higher power densities by developing technologies that increase operational efficiency and reduce vampire power,” says Ahsan Zaman, Silanna Semiconductor’s director of product marketing. “By building production-ready reference designs around these technologies we are also simplifying the design-to-manufacturing cycle to ensure these advanced charger designs move to production in the shortest possible time.”

The SZ1131 operates at frequencies up to 146kHz and provides the ease-of-design of a simple flyback controller with all the benefits of an ACF design. This includes recycling the leakage inductance energy of the flyback transformer and limiting the primary FET drain voltage spike during turn-off events. Employing Silanna Semiconductor’s OptiModeTM digital control architecture, the SZ1131 adjusts the device’s mode of operation on a cycle-by-cycle basis to maintain high efficiency, low EMI, fast dynamic load regulation, and other key power supply parameters in response to varying line voltage and load conditions.

Supplied in a 16-pin SOIC package, the SZ1131 offers protection against over-temperature, over-voltage, over-current, over-power, output short circuit, and transformer core saturation faults without the need for additional external components.

To further speed designs based on the RD-31 all PCB Gerber files and production files are available on request.
