AT1368

1-Channel Synchronous Buck PWM Controller

with Power Good Reset

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, output adjustment, monitoring and

protection functions into a single package. The

output voltage of the converter can be precisely

regulated with a maximum tolerance of

鹵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.

Features

鈥?High efficiency (min. 90% On IO=300mA

~600mA)

鈥?Using external P and N channel MOSFET

鈥?Supports for down and up/down Zeta

conversion

鈥?Maximum Duty 100%

鈥?Oscillation frequency 300KHz or 600KHz

鈥?Soft Start by an external capacity

鈥?Output voltage accuracy

鹵2%

鈥?Built-in ON/OFF Function

鈥?Built-in Short-circuit Protection

鈥?Stand-by current max. 10碌A(chǔ)

鈥?Quiescent Current 1mA

鈥?Monitor the input voltage and 3V3 output

鈥?Input voltage: 2.5V ~7.0V

Applications

鈥?Slim-Type CD-ROM/DVD-ROM/CD-RW

鈥?Power Supply for portable devices

鈥?Main or Sub Power source foe notebook

computers and peripherals.
