NCP1423, SCV1423 Boost Converter - Sync-Rect, PFM, DC-DC, True-Cutoff, Ring-Killer 400 mA NCP1423 is a monolithic micropower high frequency step up switching converter IC specially designed for battery operated hand held electronic products. 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. When the IC is disabled, in.
