1 Introduction
The Texas Instruments TPS75003EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the TPS75003 multi-channel power IC. This device has two buck controllers and a low
dropout linear regulator. The device will operate at input voltages between 2.2 V and 6.5 V. The buck
controllers can provide output voltages between 1.22 V and the input voltage and output currents up to 3
A. This EVM is specifically designed and optimized to operate from a 5 V input with output currents up to
2 A for V
OUT1
= 1.2 V typical and V
OUT2
= 3.3 V typical. In addition, the EVM is jumper configurable so that
each output can be independently enabled or the outputs can be sequenced in the following order: V
OUT3
,
V
OUT2
then V
OUT1
.
