AIC1401 Datasheet | Analog Intergrations Corporation

PWM Step-Down Switching Controller with Shutdown n Features l l l l l n DESCRIPTION The AIC1401 is a high efficiency, PWM stepdown, voltage-mode, switching controller. It is suitable for IA, Notebook, LCD PC and LCD monitor main power applications. The built-in high voltage CMOS driver drives an external N-channel MOSFET for replacing the higher cost P-channel MOSFET in a standard buck topology. The 200KHz switching frequency allows using smaller external ponents while maintaining high conversion ensures efficiency. the The 11MHz converter bandwidth and 6V/us slew rate of the error amplifier higher bandwidth and the fast transient response. The AIC1401 also Features over...
