Beschreibung

The LM5149-Q1EVM-2100 evaluation module (EVM) is a synchronous buck DC/DC regulator that employssynchronous rectification to achieve high conversion efficiency in a small footprint. It operates over a wide input voltage range of V to 80 V, providing a regulated output of 5 V. The output voltage has better than 1% setpoint accuracy and are adjustable by modifying the feedback resistor values, permitting the user to customize the output voltage from 2.5 V to 12 V as needed.
