The latest DC/DC product family delivers industry leading game changing family of buck regulators  

San Diego, CA – November 18th, 2020 – Silanna Semiconductor, The Power Density Leader, today announced the launch of their newest family of wide voltage, high frequency point of load converters targeting USB-PD applications.  Silanna Semiconductor focuses on ultimate Power Management challenges with best in class power density and efficiency performance that delights customers with unprecedented BoM savings.    

SZPL3102A/3103A family of two DC-DC converters (Buck Regulators) operate up to 2MHz.  Delivering industry leading wide input and output range converters that support up to 27VDC input in a tiny 3mm X 3mm QFN.  

Tim Wilhelm, Director of Marketing, explained, “Higher switching frequency means a smaller, lower cost output filter that has delighted the clients we have sampled.  The SZPL3102/3103 have ground-breaking efficiencies in the smallest size and weight designs. Our support tools give customers the flexibility and confidence to quickly increase the performance efficiency which ultimately increases the power density in their designs approaching 12% of the volume required by low frequency competitive solutions.  The SZPL3102/3103 significantly reduce BOM cost, design cycles and time to market.”  

The SZPL3102A and SZPL3103A have unique features that optimize their performance in USB port power supply applications. Extremely low operating power dissipation enables very low no-load power that is an important specification for regulatory certification. Furthermore, the SZPL3102A contains a momentary internal feedback path that 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.  

“At Silanna Semiconductor we have the mantra ‘Power Management Re-Imagined’ and this family of DC/DC convertors is one more example, we approached the size cost challenge completely differently than our competitors,” said Mark Drucker, CEO of Silanna Semiconductor. “Our design team increased the frequency to 2MHz and maintained highest efficiency and power density which allowed unheard of size and cost reductions.  We are witnessing some fantastic customer reactions, which have resulted in a great deal of early design wins particularly in USB-PD applications.”  

Silanna incorporated internal and external Resistor Divider flexibility for custom design support.  The SZPL3102 Includes a momentary internalFB Resistor Divider that allows time for some PD controllers to power up and take smooth control.  The SZPL3103 allows for external FB Resistor divider for stand-alone operation and co-operation with other USB port controllers using an external divider network. 

Key Features:  

  • Optimal for USB PD and Fast Charging 
  • 18W, 27W, 45W up to 65W PD-ports  
  • Up to 2 MHz Switching Frequency for Compact Designs
  • 3.3V to 21V Output at 3.25A (covers USB-PD 3.0 and PPS applications)  
  • 8V to 27V Input    
  • Dual Input LDOs (VIN and VOUT) for Product Bias Optimizes Overall Efficiency  
  • Space saving 3mm x 3mm QFN package   

 Key Applications  

  • USB-PD and Fast Charging Power Adapters 
  • High Power Density DC/DC Power Supplies 
  • High Efficiency Power Adapters 
  • Battery Chargers for Mobile Devices  

Availability:  

SZPL3102A/3103A family are being sampled to key accounts and will be fully released later this year. More information and visuals are available at https://www.powerdensity.com or contact sales@silannasemi.com

    First of all I want to say wonderful blog! I had a quick question which I’d
    like to ask if you don’t mind. I was interested to find
    out how you center yourself and clear your thoughts
    before writing. I have had a hard time clearing
    my thoughts in getting my ideas out. I do take pleasure in writing however it just seems
    like the first 10 to 15 minutes tend to be lost just trying to figure out
    how to begin. Any recommendations or tips?
    Thanks!
