The LM5575MHX/NOPB is a 75V, 1.5A, synchronous step-down switching regulator manufactured by Texas Instruments. It utilizes a high-side FET and a low-side FET for efficient and high power density conversion. The device contains integrated loop compensation and operational amplifiers to reduce the external component count. It has an adjustable output current limit and provides protection from over voltage, over temperature, and output overcurrent. The LM5575MHX/NOPB is suitable for automotive, medical, consumer, industrial, and other general applications.
