1- Channel Synchronous Buck PWM Controller

General Description

The AT1392 provides complete control and

protection for a DC/DC converter optimized for

high-performance microprocessor applications. It

is designed to drive one P-Channel and one

N-Channel in a buck topology. The AT1392

integrates all of the control, output adjustment into

a single package. The output voltage of the

converter can be precisely regulated with a

maximum tolerance of ±2% over temperature and

line voltage variations. The AT1392 is a family of

low-noise

converters that is ideally suited for systems

powered from a 1-cell Li-ion battery or from a

3-cell to 4-cell NiCd, NiMH, or alkaline battery. It

can also be used to USB-Based power system.
