AIC1401

The AIC1401 is a high efficiency, PWM step-down, 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 components while maintaining high conversion efficiency. The 11MHz bandwidth and 6V/us slew rate of the error amplifier ensures the higher converter bandwidth and the fast transient response. The AIC1401 also features over current protection. AIC1401  provides adjustable over current trigger point and short-circuit protections by sensing the output current across the on resistance of the external N-channel MOSFET rather then an expensive external low value sense resistor
