Features
Wide input buck converter for delivering power from poorly-regulated supplies
USB Type-C PD (Power Delivery) Source supporting 20-V at 3-A, 15-V at 3-A, 9-V at 3-A, or 5-V at 3-A outputs
96.8% maximum efficiency at 48-V input and full load
External SPI Flash removes the need for microcontroller host device
Optional microcontroller for easy programming of USB Type-C PD controller serial peripheral interface (SPI) Flash over USB Micro-B
