________________Ge n e ra l De s c rip t io n  
____________________________Fe a t u re s  
The MAX1639 is an ultra-high-performance, step-down  
DC-DC controller for CPU power in high-end computer  
systems. Designed for demanding applications in which  
output voltage precision and good transient response are  
critical for proper operation, it delivers over 35A from 1.1V  
to 4.5V with ±1% total accuracy from a +5V ±10% supply.  
Excellent dynamic response corrects output transients  
caused by the latest dynamically clocked CPUs. This  
controller achieves over 90% efficiency by using synchro-  
nous rectification. Flying-capacitor bootstrap circuitry  
drives inexpensive, external N-channel MOSFETs.  
♦ Better than ±1% Output Accuracy Over  
Line and Load  
♦ Greater than 90% Efficiency Using N-Channel  
MOSFETs  
♦ Pin-Selected High Switching Frequency:  
300kHz, 600kHz, or 1MHz  
♦ Over 35A Output Current  
♦ Resistor-Divider Adjustable Output from  
1.1V to 4.5V  
♦ Current-Mode Control for Fast Transient  
Response and Cycle-by-Cycle Current-Limit  
Protection  
The switching frequency is pin-selectable for 300kHz,  
600kHz, or 1MHz. High switching frequencies allow the  
use of a small surface-mount inductor and decrease out-  
put filter capacitor requirements, reducing board area  
and system cost.  
♦ Short-Circuit Protection with Foldback Current  
Limiting  
Output overvoltage protection is enforced by a crowbar  
circuit that turns on the low-side MOSFET with 100%  
duty factor when the output is 200mV above the normal  
regulation point. Other features include internal digital  
soft-start, a power-good output, and a 3.5V ±1% refer-  
ence output. The MAX1639 is available in a 16-pin  
narrow SOIC package.  
♦ Crowbar Overvoltage Protection  
♦ Power-Good (PWROK) Output  
♦ Digital Soft-Start  
♦ High-Current (2A) Drive Outputs
