Highest Efficiency + Power Density
DC/DC Converters with
Radical Solution Size + Cost Reductions 

SZPL3102A | SZPL3103A

Announcing the launch of our 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 2 MHz. Delivering industry leading wide input and output range converters that support up to 27VDC input in a tiny 3 mm X 3 mm QFN.  

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 3 mm x 3 mm QFN package 

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.

Silanna incorporated internal and external Resistor Divider flexibility for custom design support. The SZPL3102 includes a momentary internal FB 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. 

Applications:

  • USB PD and Fast Charging Power Adapters 

  • High Power Density DC/DC Power Supplies 

  • High Efficiency Power Adapters 

  • Battery Chargers for Mobile Devices
