VP300 - USB PD Wall Adapter

Description



 
The VP300 is a USB Type-C and USB Power Delivery (USB PD) 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 contollers. Integrated discharge MOSFET and built-in Vbus PMOS pre-drive control save external components. Fully integrated protection includes UVP, OVP, OCP, SCP, and over temperature protection.
