AIC1569A

5-bit DAC, Synchronous PWM Power Regulator

ꢀ FEATURES

ꢀ DESCRIPTION

ꢀ Compatible with HIP6004.

The AIC1569A is a high power, high efficiency

switching regulator controller optimized for high

performance microprocessor applications. It is

designed to drive dual N-channel MOSFETs in a

standard synchronous buck topology. Featuring

a digitally programmable switching regulator, the

AIC1569A includes monitoring and protection

capabilities in addition to all the essential

synchronous PWM control functions.

ꢀ Simple Voltage-Mode PWM Control.

ꢀ Dual N-Channel MOSFET Synchronous Drive.

ꢀ Fast Transient Response.

ꢀ

1% 5-Bit Digital-to-Analog Output Voltage.

ꢀ Adjustable Current Limit Without External

Sense Resistor.

ꢀ Full 0% to 100% Duty Ratio.

ꢀ 200KHz

Free-Running

Oscillator,

Programmable up to 350KHz.

ꢀ Power-Good Output Voltage Monitor.

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% over temperature and line

voltage shifts.

ꢀ APPLICATIONS

ꢀ Power Supply for Pentium® II, Power® and

Alpha® Microprocessors.

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

ꢀ Low-Voltage Distributed Power Supplies.

The internal oscillator of the AIC1569A 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 an 11MHz

bandwidth and 6V/µS slew rate, which enables

high converter bandwidth for fast transient

response.

The AIC1569A provides adjustable over current

and short circuit protections. It senses the output

current across the on resistance of the upper N-

channel MOSFET without an external low value

sense resistor. It also monitors the output voltage

with a window comparator and issues a power

good signal when the output is within 10% of the

rated output voltage.
