NCP1411
Sync−Rect PFM Step−Up
DC−DC Converter with
Low−Battery Detector and
Ring−Killer
NCP1411 is a monolithic micropower high frequency Boost (step−up) voltage switching converter IC specially designed for battery operated hand−held electronic products up to 250 mA loading. 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. Low−Battery Detector, Logic−Controlled Shutdown and Cycle−by−Cycle Current Limit provide value−added features for various battery−operated applications. The innovative Ring−Killer circuitry guarantees quiet operation in discontinuous conduction mode.
