TPS211xADRB EVM, Power Multiplexer Evaluation Module
1
Introduction
The TPS211xA EVM is an evaluation module for the Texas Instruments TPS211xA family of two-input,
one-output power multiplexers. These multiplexers enable seamless transition between two power
supplies, each operating at 2.8 V-5.5 V and delivering up to 1 A. TPS211xA EVM-061 is used for
TPS211xAPW packaged parts. The TPS211xA EVM-581 is used for TPS211xADRB packaged parts and
described in this user's guide which contains the EVM schematics, board layout, list of materials and
configuration materials.

The EVM has test points for convenient access to all critical node voltages, potentiometers for adjusting
the current limit and the auto-switching voltage sense thresholds, headers for selecting the
manual/auto-switching operating modes, and headers for selecting the output hold-up capacitance.
