TPS628690EVM-135 Evaluation Module
This user's guide describes the characteristics, operation, and use of TI's evaluation module (EVM) for
the TPS628690, TPS628680 devices. The TPS628690EVM-135 (BSR135) facilitates the evaluation of the
TPS628690, 6-A step-down converter with DCS-Control
The EVM creates output voltages between 0.2 V and 0.8375 V with 1% accuracy output voltages from higher
input voltages between 2.4 V and 5.5 V. The TPS628690 is a highly efficient and tiny solution for point-of-load
(POL) converters for space-constrained applications, such as artificial intelligence chips, camera modules, solid
state drives (SSDs), LPDDR5 memory, and optical modules.
