This document is the user guide for the TPS66020 Evaluation Module (TPS66020EVM). The
TPS66020EVM allows for evaluation of the TPS66020 IC as part of a stand-alone testing kit and testing of
USB Type-C and Power Delivery (PD) end products. Out of the box, the TPS66020EVM can be used to
test the Source and Sink paths in addition to trying the different protection schemes, such as OVP
(Overvoltage Protection).

Introduction
Texas Instrument's (TI's) TPS66020 evaluation module helps designers evaluate the operation and
performance of the TPS66020 device.
The TPS66020 is a full-featured power switch multiplexer that contains an integrated 5-V Source power
path and a 4-V to 22-V Sink power path. The 5-V Source path limits the output current to a safe level by
operating in a constant-current mode when the output load exceeds the selected current-limit threshold.
Each power path supports overtemperature and reverse current protection. VBUS has overvoltage
protection with its level being set by an optional external resistor divider. If no overvoltage protection is
desired, it may be disabled by grounding the OVP terminal. The TPS6602x series supports a fault pin that
indicates overcurrent and overtemperature events.
The TPS66020EVM has jumpers, header and test points that will permit to test the Source and Sink
configuration in addition to the protection schemes.
