LM5160A 65V, 1.5A synchronous buck converter with integrated high-side and low-side MOSFETs is the industry’s highest power synchronous buck regulator and supports TI’s innovative Fly-Buck™ topology to deliver isolated bias supplies up to 15W with no opto-isolator.
LM5160A offers great flexibility which enables direct point-of-load regulation from a wide input voltage range of 4.5V to 65V and also simplifies isolated DC/DC designs by enabling very good output regulation with no opto-coupler required.
