NCP1450A  
PWM Step−up DC−DC  
Controller  
The NCP1450A series are PWM step-up DC-DC switching  
controller that are specially designed for powering portable equipment  
from one or two cells battery packs. The NCP1450A series have a  
driver pin, EXT pin, for connecting to an external transistor. Large  
output currents can be obtained by connecting a low ON-resistance  
external power transistor to the EXT pin. The device will  
automatically skip switching cycles under light load condition to  
maintain high efficiency at light loads. With only six external  
components, this series allows a simple means to implement highly  
efficient converter for large output current applications.  
Each device consists of an on-chip PWM (Pulse Width Modulation)  
oscillator, PWM controller, phase- compensated error amplifier,  
soft-start, voltage reference, and driver for driving external power  
transistor. Additionally, a chip enable feature is provided to power  
down the converter for extended battery life.
