FS1404-3300-AS

FS1404-3300-AS is an easy-to-use, fully integrated, and highly efficient micro-point-of-load (µPOL™) voltage regulator. The on-chip pulse-width modulation (PWM) controller and integrated MOSFETs, plus incorporated inductors 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 practices and uses class-leading technologies. From early in the integrated circuit design phase, designers worked with application and packaging engineers to select compatible technologies and implement them in ways that reduce compromise. Applications include storage applications, telecom and networking applications, industrial applications, server applications, distributed point-of-load power architectures, computing peripheral voltage regulation, and general DC-DC conversion.
