VP302 – USB Type-C and USB PD Controller for SMPS


The VP302 is a USB Type-C and USB PD Controller with highly integrated function for Switching Mode Power Supply (SMPS). One 8051 MCU is embedded to support PD 3.0 and Power Integrations InnoSwitch3-Pro’s I2C command protocol.

VP302 integrates 10 bit ADC for VBus monitor and supports thermal detection with external NTC for power system temperature monitor and protection. Vconn switch is built-in, and CC pins could provide the Vconn power for E-Marker Controllers. VP302 has passed USB-IF PD 3.0 and PPS certification, TID: 1000130.
