NCP1423  
400 mA Sync−Rect PFM  
Step−Up DC−DC Converter  
with True−Cutoff and  
Ring−Killer  
http://onsemi.com  
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,  
internal conduction path from LX or BAT to OUT is blocked, OUT pin  
is isolated from the battery. This achieves True−Cutoff. Ring−Killer is  
also integrated to eliminate the high frequency ringing in discontinuous  
conduction mode. Low−Battery Detector, Cycle−by−Cycle Current  
Limit, Overvoltage Protection and Thermal Shutdown provide  
value−added features for various battery operated application. With all  
of these functions ON, the quiescent supply current is only 9.0 mA. This  
device is available in compact Micro10 package.
