SZPL3102A

Offering output powers up to 65W, the SZPL3102A is a wide-voltage, high-frequency point of load converter 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.

The SZPL3102A converter (Buck Regulator) operates 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.

• 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 has unique features that optimize its 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.

• USB PD and Fast Charging Power Adapters 

• High Power Density DC/DC Power Supplies 

• High Efficiency Power Adapters 

• Battery Chargers for Mobile Devices
