MAX1639规格书详情
General Description
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.
特性 Features
♦ 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
♦ Short-Circuit Protection with Foldback Current Limiting
♦ Crowbar Overvoltage Protection
♦ Power-Good (PWROK) Output
♦ Digital Soft-Start
♦ High-Current (2A) Drive Outputs
Applications
Local DC-DC Converters for CPUs
Workstations
Desktop Computers
LAN Servers
GTL Bus Termination
