Evaluation Module for TPS62737 Ultra Low Power Buck
This user's guide describes the TPS62737 evaluation module (EVM). The TPS62737 device is a high-
frequency synchronous stepdown dc-dc converter optimized for ultralow-power energy harvesting
applications. The converter can provide up to 2900 mA of continuous current to a 1.3- to 5.3-V output from
input voltages up to 5.5 V.
