Design files

Overview

This is a power bank reference design with a USB type C DFP plus a USB type A port supporting high voltage discharging. Fast charger input is also supported to save more charging time. It can detect the input port attach/detach automatically, as well as the output ports.

Features
  • Type C DFP Enabled @5V/3A
  • Fast Charger input supported
  • Fast Discharging with high voltage output
  • Automatic Attach/Detach Detection
  • High Discharging Current
  • High Integration and Low BOM
