Dynamically Adjustable, Synchronous

Step-Down Controller for Notebook CPUs

General Description

Features

The MAX1717 step-down controller is intended for core

CPU DC-DC converters in notebook computers. It fea-

tures a dynamically adjustable output, ultra-fast tran-

sient response, high DC accuracy, and high efficiency

needed for leading-edge CPU core power supplies.

Maxim’s proprietary Quick-PWM™ quick-response,

constant-on-time PWM control scheme handles wide

input/output voltage ratios with ease and provides

100ns “instant-on” response to load transients while

maintaining a relatively constant switching frequency.

♦ Quick-PWM Architecture

♦ ±±1 ꢀ Accuracy Over Line and Load

OUT

♦ 5-Bit On-Board DAC with Input Mux

♦ Precision-Adjustable ꢀ Slew Control

OUT

♦ 0.925ꢀ to 2ꢀ Output Adjust Range

♦ Supports ꢀoltage-Positioned Applications

♦ 2ꢀ to 28ꢀ Battery Input Range

♦ Requires a Separate +5ꢀ Bias Supply

♦ 200/300/550/±000kHz Switching Frequency

♦ Over/Undervoltage Protection

The output voltage can be dynamically adjusted

through the 5-bit digital-to-analog converter (DAC)

inputs over a 0.925V to 2V range. A unique feature of

the MAX1717 is an internal multiplexer (mux) that

accepts two 5-bit DAC settings with only five digital

input pins. Output voltage transitions are accomplished

with a proprietary precision slew-rate control^†that mini-

mizes surge currents to and from the battery while

guaranteeing “just-in-time” arrival at the new DAC setting.

♦ Drives Large Synchronous-Rectifier FETs

♦ 700µA (typ) I

Supply Current

♦ 2µA (typ) Shutdown Supply Current

♦ 2ꢀ ±±1 Reference Output

♦ ꢀGATE Transition-Complete Indicator

♦ Small 24-Pin QSOP Package

High DC precision is enhanced by a two-wire remote-

sensing scheme that compensates for voltage drops in

the ground bus and output voltage rail. Alternatively,

the remote-sensing inputs can be used together with

the MAX1717’s high DC accuracy to implement a volt-

age-positioned circuit that modifies the load-transient

response to reduce output capacitor requirements and

full-load power dissipation.

Single-stage buck conversion allows these devices to

directly step down high-voltage batteries for the highest

possible efficiency. Alternatively, two-stage conversion

(stepping down the +5V system supply instead of the

battery) at a higher switching frequency allows the mini-

mum possible physical size.
