High-Speed Step-Down Controller

for Notebook Computers

General Description

Features

The MAX1714 pulse-width modulation (PWM) controller

provides the high efficiency, excellent transient

response, and high DC output accuracy needed for

stepping down high-voltage batteries to generate low-

voltage CPU core or chip-set/RAM supplies in notebook

computers.

ꢀ Ultra-High Efficiency

ꢀ No Current-Sense Resistor (Lossless I

)

LIMIT

ꢀ Quick-PWM with 100ns Load-Step Response

ꢀ 1% V Accuracy Over Line and Load

OUT

ꢀ 2.5V/3.3V Fixed or 1V to 5.5V Adjustable Output

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.

Range

ꢀ 2V to 28V Battery Input Range

ꢀ 200/300/450/600kHz Switching Frequency

ꢀ Overvoltage Protection (MAX1714A)

ꢀ Undervoltage Protection

The MAX1714 achieves high efficiency at a reduced

cost by eliminating the current-sense resistor found in

traditional current-mode PWMs. Efficiency is further

enhanced by an ability to drive very large synchronous-

rectifier MOSFETs.

ꢀ 1.7ms Digital Soft-Start

ꢀ Drives Large Synchronous-Rectifier FETs

ꢀ 2V 1% Reference Output

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.

ꢀ Power-Good Indicator

Ordering Information

The MAX1714 is intended for CPU core, chipset,

DRAM, or other low-voltage supplies as low as 1V. The

MAX1714A is available in a 20-pin QSOP package and

includes overvoltage protection. The MAX1714B is

available in a 16-pin QSOP package with no overvolt-

age protection. For applications requiring VID compli-

ance or DAC control of output voltage, refer to the

MAX1710/MAX1711 data sheet. For a dual output ver-

sion, refer to the MAX1715^†data sheet.
