TDK FS1404-2500-AL

The 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.

The ability to program aspects of the FS1404's operation using the Inter-Integrated Circuit (I²C) protocol is unique in this class of product. Developing and optimizing all of these elements together has yielded the smallest, most efficient and fully featured 4A µPOL™ currently available.

The built-in protection features include pre-biased start-up, soft-start protection, over-voltage protection, thermally compensated over-current protection with hiccup mode, thermal shut-down with auto-recovery.
