36W USB Dual Port USB Type-C™ PD Reference Design with Port Power Management DC/DC Charger


Design files


The PMP20172 reference design provides up to 36W on two USB Type-C outputs.  Input is a 17VDC bus.  The two outputs implement port power management.  If only one port is in use, it is allocated the full 36W.  If both ports are in use, power is split into 18W on each port.  Output voltages of 5V, 9V, or 15V are supported. The PMP20172 has been certified as a power brick by the USB-IF (Product Test ID: 1020023).
