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 22W/inch³, the RD-23 operates with a peak efficiency of over 92% and has a no-load power consumption (@ 230Vac) below 20mW. Efficiency is flat across the universal input (90 – 265Vac) input range and the reference design is fully production-ready as it exceeds conducted and radiated EMI requirements by more than 6dB margins.

“The RD-23 is the latest in a series of silicon- and GaN-based reference designs that Silanna has created to help engineers quickly and easily develop the industry’s most efficient and highest power density chargers,” comments Ahsan Zaman, Silanna Semiconductor’s director of product marketing. “In our benchmarking tests the RD-23 met and exceeded both the efficiency and no-load vampire power consumption of the best-in-class commercially available GaN-based power adapters. RD-23 demonstrates GaN-level performance at silicon-level costs.”

The SZ1131 operates at frequencies of 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 OptiMode^TMdigital 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.

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

Silanna Semiconductor Powers the Highest Performance Fast Charging AC/DC Power Adapters

The Power Density Leader partners with Heincro Technology to
launch leading 65W 2C1A Multi-Port Charger

Silanna Semiconductor, The Power Density Leader, today announced their partnership with Heincro Technology to launch an industry breakthrough all-silicon 65W 2C1A Multi-Port Fast Charger. Silanna Semiconductor focuses on the ultimate power management challenges with the best-in-class power density and efficiency that delight customers with unprecedented BoM savings. Heincro Technology partnered with Silanna Semiconductor by utilizing their AC/DC active clamp flyback (ACF) controller.

The full production of Silanna’s ACF controller started in mid-2020 and is continuing to make a huge impact in the technology sector with power supply and technology companies becoming increasingly interested in the product's high efficiency and power density. The ACF architecture reduces BOM cost by not only integrating the ACF circuit but also enabling designers to use a lower-cost transformer, SR FET, clamp capacitor, and input filter.

“The all-silicon design combines the simplicity of traditional flyback controllers with the efficiency and power density enabled by ACF controllers,” said Larry Wasylin, Vice President of Worldwide Sales at Silanna Semiconductor. “It is exciting for the team at Silanna Semiconductor to see Heincro Technology achieve their goals of record-high efficiency and power density in their extremely slim and compact 65W 2C1A multi-port charger using our active clamp flyback controller.”

Silanna’s ACF is well suited for designing compact adapters for powering notebooks, video game consoles, and multi-port wall chargers, meaning it is highly desirable for power supply and technology companies to utilize in their products. Heincro Technology is one of many technology companies to take advantage of this breakthrough product.

“Heincro Technology was seeking to overcome the technology hurdle of delivering the highest performance at the lowest cost structure our consumers required for our 65W 2C1A multi-port charger. We were extremely attracted to the solution from Silanna Semiconductor as not only is it the best Power IC but it also delivers on our challenge," said Haibin Xiao, CTO of Heincro Technology. “We are delighted to bring to the market this exciting dual-port fast charger for our customers’ devices such as smartphones and laptops.”
