TPS62866EVM-051 Evaluation Module
ABSTRACT
The TPS62866EVM-051 facilitates the evaluation of the TPS62866 6-A, step-down converter with DCS-Control
™
in a tiny 1.05-mm by 1.78-mm WCSP package with 0.35-mm pitch. The EVM outputs a 0.9-V output voltage with
1% accuracy from input voltages between 2.4 V and 5.5 V. The TPS62866 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), and optical modules.
