TPS62851xEVM-139 Evaluation Module
TheTPS62851xEVM-139 facilitates the evaluation of the TPS62851x 0.5-A, 1-A and 2-A pin to pin compatible
step-down converters in a 2.1-mm × 1.6-mm (including pins) in SOT583 package. BSR139-001 uses the 2-A
TPS628512 device, BSR139-002 uses the 1-A TPS628511 device and BSR139-003 uses the 0.5-A TPS628510
device. The EVMs regulate the output voltage to 1.8 V from input voltage from 2.7 V to 6 V. This user's guide
describes the characteristics, operation, and use of the TPS62851xEVM-139 Evaluation Module (EVM) with a
complete schematic diagram, printed circuit board layouts, and bill of materials are included in this document.
