General Description
The WT6632F (Standard Code Version) is a highly integrated USB Power Delivery (PD) controller built-in with
®
TM
Weltrend’s proprietary standard codes that supports USB PD 2.0 specifications and Qualcomm Quick Charge
3.0 technology designed for USB Type-C charging applications such as travel adapters, chargers, etc. It
minimizes external components by integrating USB PD baseband PHY, Type-C detection, shunt regulator,
voltage and current monitors, and control circuits of blocking MOSFET to allow small form factor and low BOM
cost. It supports wide operation range from 4V to 30V without the need of an external LDO.
