AIC1401

PWM Step-Down Switching Controller with

Shutdown

n FEATURES

n DESCRIPTION

l Operation Voltage up to 15V

l Voltage-Mode Operation

l Fast Transient Response

The AIC1401 is a high efficiency, PWM step-

down, voltage-mode, switching controller. It is

suitable for IA, Notebook, LCD PC and LCD

l Built In Accurate 1.3V Voltage Reference

monitor main power applications.

l Adjustable Over Current Protection using

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.

R_DS(ON)No External Current Sense Resistor

Required

l Low Shutdown Current

l 200KHz Free-Running Oscillator

l Built in Soft Start.

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

n APPLICATIONS

l Notebook PC

l Advanced PC Mboards

l Information PCs

l Servers and Workstations

l PC Add-On Cards

amplifier

ensures

the

higher

converter

bandwidth and the fast transient response.

The AIC1401 also features over current

protection. It 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.
