AIC1570

5-bit DAC, Synchronous PWM Power Regulator

with LDO and Linear Controller

FEATURES

DESCRIPTION

ꢀ

Compatible with HIP6018.

ꢀ

The AIC1570 combines a synchronous voltage

mode controller with a low dropout linear regulator

and a linear controller as well as the monitoring and

protection functions in this chip. The PWM

controller regulates the microprocessor core

voltage with a synchronous rectified buck converter.

The linear controller regulates power for the GTL

bus and the linear regulator provides power for the

clock driver circuit.

Provides

Regulated Voltages for Micro-

ꢀ

processor Core, Clock and GTL Power.

Simple Voltage-Mode PWM Control.

Dual N-Channel MOSFET Synchronous Driver.

Operates from +3.3V, +5V and +12V Inputs.

Fast Transient Response.

ꢀ

Full 0% to 100% Duty Ratios.

±1.0% Output Voltage for VCORE and 2.0%

Output Voltage Reference for VCLK and VGTL.

TTL Compatible 5-bit Digital-to-Analog Core

Output Voltage Selection. Range from 1.3V to

3.5V.

0.1V Steps from 2.1V to 3.5V.

0.05V Steps from 1.3V to 2.05V.

Adjustable Current Limit without External Sense

Resistor.

Microprocessor Core Voltage Protection against

Shorted MOSFET.

An integrated 5 bit D/A converter that adjusts the

core PWM output voltage from 2.1V to 3.5V in 0.1V

increments and from 1.3V to 2.05V in 0.05V

increments. The linear regulator uses an internal

driver device to provide 2.5V±2.5%. The linear

controller drives with an external N-channel

MOSEFET to provide 1.5V±2.5%.

ꢀ

This chip monitors all the output voltages. Power

Good signal is issued when the core voltage is

within ±10% of the DAC setting and the other levels

are above their under-voltage levels. Over-voltage

protection for the core output uses the lower N-

channel MOSFET to prevent output voltage above

115% of the DAC setting.

Power Good Output Voltage Monitor.

Over-Voltage and Over-Current Fault Monitors.

200KHz Free-Running Oscillator Programmable

up to 350KHz.

ꢀ

The PWM over-current function monitors the output

current by using the voltage drop across the upper

MOSFET’s R_DS(on), eliminating the need for a

current sensing resistor.

APPLICATIONS

Full Motherboard Power Regulation for

ꢀ

Computers.
