Fe a t u re s

The MAX1710/MAX1711 s te p -d own c ontrolle rs a re

intended for core CPU DC-DC converters in notebook

computers. They feature a triple-threat combination of

ultra-fast transient response, high DC accuracy, and

hig h e ffic ie nc y ne e de d for le a d ing-e dg e CPU c ore

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 fre-

quency.

♦ 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

♦ 4-Bit On-Board DAC (MAX1710)

♦ 5-Bit On-Board DAC (MAX1711)

♦ 0.925V to 2V Output Adjust Range (MAX1711)

♦ 2V to 28V Battery Input Range

High DC precision is ensured by a 2-wire remote-sens-

ing scheme that compensates for voltage drops in both

ground bus and the supply rail. An on-board, digital-to-

analog converter (DAC) sets the output voltage in com-

pliance with Mobile Pentium II^®CPU specifications.

♦ 200/300/400/550kHz Switching Frequency

♦ Remote GND and V

Sensing

OUT

♦ Over/Undervoltage Protection

♦ 1.7ms Digital Soft-Start

The MAX1710 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.

♦ Drives Large Synchronous-Rectifier FETs

♦ 2V ±1% Reference Output

♦ Power-Good Indicator

Single-stage buck conversion allows these devices to

directly step down high-voltage batteries for the highest

possible efficiency. Alternatively, 2-stage conversion

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

battery) at a higher switching frequency allows the mini-

mum possible physical size.

The MAX1710 and MAX1711 are identical except that

the MAX1711 has a 5-bit DAC rather than a 4-bit DAC.

Also, the MAX1711 has a fixed overvoltage protection
