NCP1421  
600 mA Sync−Rect PFM  
Step−Up DC−DC Converter  
with True−Cutoff and  
Ring−Killer  
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, small−sized inductor and output capacitor to be  
used. When the device is disabled, the internal conduction path from  
LX or BAT to OUT is fully blocked and the OUT pin is isolated from  
the battery. This True−Cutoff function reduces the shutdown current  
to typically only 50 nA. Ring−Killer is also integrated to eliminate  
the high−frequency ringing in discontinuous conduction mode. In  
addition to the above, Low−Battery Detector, Logic−Controlled  
Shutdown, Cycle−by−Cycle Current Limit and Thermal Shutdown  
provide value−added features for various battery−operated  
applications. With all these functions on, the quiescent supply  
current is typically only 8.5 m A. This device is available in the  
compact and low profile Micro8t package.
