FS1703-3300-AS

FS1703-3300-AS is a 3A rated µPOL™ buck regulator with integrated inductor. It is an easy-to-use, fully integrated and highly efficient micro-point-of-load voltage regulator. The on-chip pulse-width modulation controller and integrated MOSFETs, plus incorporated inductor and capacitors, result in an extremely compact and accurate regulator. The low-profile package is suitable for automated assembly using standard surface-mount equipment. Developed by a cross-functional engineering team, the design exemplifies best practice and uses class-leading technologies. From early in the integrated circuit design phase, designers worked with application and packaging engineers to select compatible technology and implement them in ways that reduce compromise. Application includes storage, telecom, wireless and 5G, networking and datacentre, industrial, distributed point-of-load power architectures, computing peripheral voltage regulation and general DC-DC conversion.
