USB PD Controller Series
Stand-Alone PD Controller for Sink
BD93E11GWL EVK
BD93E11GWL-EVK-001 (Stand-Alone)
Introduction
The User’s Guide describes the series of required procedures to operate and evaluate the EVK of the PD controller BD93E11GWL
for Sink. The document also contains the circuit components, the operating procedures, and the Application Data.
Overview
BD93E11GWL-EVK-001 implements Stand-Alone PD Controller IC of BD93E11GWL in Sink mode. This EVK performs the Type-
C connection and make PD contracts with the attached Source device according to the configuration of the DIP switches on the
board. The EVK assumes Stand-Alone operation in the Dead Battery mode, so this EVK does not need an external power source
and works as a VBUS powered product. The board will supply power and voltage via VSNK terminal based on the negotiation
contracted with the source. Therefore, any existing board that is powered by an AC adapter or a regulated power supply up to
80W/20V can work and be evaluated with the EVK as a Type-C/PD power source.
