The TDK FS1404 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 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.
