NCP1422 is a monolithic micropower high frequency step-up switching converter IC specifically designed for battery-operated hand-held electronic products up to 800mA 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. When the device is disabled, the internal conduction path from LX or BAT to OUT is fully blocked and the OUT pin is isolated from the battery.
