EVM User's Guide: TPS628523HAQEVM-070
TPS62852X-Q1 Buck Converter Evaluation Module
Description
The TPS628523HAQEVM-070 is designed to help
users easily evaluate and test the operation and
functionality of the TPS628521-Q1, TPS628522-
Q1 and TPS628523-Q1 buck converters. This
EVM converts a 2.7V to 6V input voltage to
a regulated 1.8V output voltage that delivers up
to 3A maximum. The IC fitted on the EVM is
TPS628523HAWDLSRQ1, which operates in a forced
PWM mode (FPWM) across the whole load current
range. The TPS628523HAQEVM-070 is available with
IC in a 2.0mm × 1.5mm QFN package.
