1- Channel Synchronous Buck PWM Controller

General Description

The AT1368 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 MOSFETs in a synchronous-rectified

buck topology. The AT1368 integrates all of the

control,

protection functions 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

AT1368 is a family of low-noise synchronous step-

down DC/DC 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.
