Overview

The LM25139-Q1 evaluation module (EVM) is a synchronous buck DC/DC regulator that employs synchronous rectification to achieve high conversion efficiency in a small footprint. The EVM operates over a wide input voltage range of 5.5V to 36V, providing a regulated output of 5V. The output voltage has better than 1% setpoint accuracy and can be adjusted by modifying the feedback resistor values.
