PWM Step−up DC−DC Controller

The NCP1450A series are PWM stepup DCDC 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 ONresistance 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 onchip Pulse Width Modulation (PWM) Oscillator PWM Controller phasecompensated error Amplifier softstart, 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.
