AIC1567

5-bit DAC, Synchronous PWM Power Regulator

with Linear Controller

ꢀFEATURES

ꢀDESCRIPTION

ꢀ

Switching Regulator and Low Dropout Linear

Regulator on single chip.

Simple Voltage-Mode PWM Control.

Dual N-Channel MOSFET Synchronous Drive.

Fast Transient Response.

1.0% 5-Bit Digital-to-Analog Output Voltage.

Adjustable Current Limit Without External Sense

Resistor.

The AIC1567 is a high power, high efficiency

switching regulator controller optimized for high

performance microprocessor applications. It is

designed to drive dual N-channel MOSFET in a

ꢀ

standard

synchronous

buck

topology.

Featuring a low dropout linear regulator and a

digitally programmable switching regulator, the

AIC1567 includes monitoring and protection

capabilities in addition to all the essential

synchronous PWM control functions.

ꢀ

Full 0% to 100% Duty Ratio.

200KHz Free-Running Oscillator Programmable

up to 350KHz.

The internal 5-bit Digital-to-Analog Converter

(DAC) adjusts the output voltage from 2.0V to

3.5V in 0.1V increments and 1.3V to 2.0V in

0.05V increments. The precision reference and

voltage-mode control can provide output

regulation within 1.0% over temperature and

line voltage shifts.

ꢀ

Power-Good Output Voltage Monitor.

Short Circuit Protection with Low Short Circuit

Output Current.

ꢀ APPLICATIONS

ꢀ

Power Supply for Pentium II, Power PC and

Alpha Microprocessors.

The internal oscillator of the AIC1567 free-runs

at 200KHz and can be adjusted up to 350KHz.

The resulting PWM duty ratio ranges from 0% to

100%. The error amplifier features a 11MHz

bandwidth and 6V/µS slew rate, which enables

high converter bandwidth for fast transient

response.

ꢀ

High-Power 5V to 3.xV DC/DC Regulators.

Low-Voltage Distributed Power Supplies.
