VP300 - USB PD Wall Adapter


The VP300 is an USB Power Delivery (USB PD) type-C controller with highly integrated function for Switching Mode Power Supply (SMPS). One 8051 MCU is embedded to support PD 3.0 and QC 3.0 protocol. VP300 could work under wide input range from 3.6V to 30V. The shut regulator is built in and 2 operational amplifiers are built in for CV and CC loop for high accuracy output for easy design. Programmable cable compensation is built in and CC pins could provide the Vconn power for E-Marker IC. Integrated discharge MOSFET and build in Vbus PMOS pre-drive control to save external components Fully integrated protect function including UVP, OVP, OCP, SCP, and over temperature protection.
