Description
- Typical Application Schematic for 2 Alkaline Cells Supply for NCP1422 800mA Sync-Rect PFM Step-Up DC-DC Converter with True-Cutoff and Ring-Killer. NCP1422 is a monolithic micropower high-frequency step-up switching converter IC specially designed for battery-operated hand-held electronic products up to 800 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
