NCP1421 Description
NCP1421 Boost Converter - Sync-Rect, PFM, DC-DC, True-Cutoff, Ring-Killer 600 mA 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,...
