NCP1421 is a monolithic micropower high-frequency step-up switching converter IC specially designed for battery- operated hand-held electronic products up to 600 mA loading. It integrates Sync-Rect to improve efficiency and to eliminate the external Schottky Diode. High switching frequency (up to 1.2 MHz) allows for a low profile, small sized inductor and output capacitor to be used.
