NCP1410 250 mA Sync-Rect PFM Step-Up DC-DC Converter with Low-Battery Detector NCP1410 is a monolithic micropower high frequency Boost (step-up) voltage switching converter IC specially designed for battery operated hand-held electronic products up to 250 mA loading.

It integrates Synchronous Rectifier for improving efficiency as well as eliminating the external Schottky Diode.

High switching frequency (up to 600 kHz) allows low profile inductor and output capacitor being used.

Low-Battery Dete
