ON Semiconductor NCP1450A DC-DC Controllers
ON Semiconductor NCP1450A DC-DC Controllers are PWM step−up DC−DC switching controllers that are specially designed for powering portable equipment from one or two cell battery packs. The NCP1450A series DC-DC Controllers from ON Semiconductor have a driver pin and 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. NCP1450A series DC-DC Controllers will automatically skip switching cycles under light load conditions to maintain high efficiency at light loads. With only six external components, the NCP1450A series allows a simple means to implement highly efficient converters for large output current applications. Applications include PDSs, MP3s, digital cameras, and electronic games.
