TPS75003EVM-092: 1.2V@2A, 3.3V@2A, 2.5V@300mA


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 VOUT1 = 1.2 V typical and VOUT2 = 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: VOUT3, VOUT2 then VOUT1.
