MAX5037 Evaluation Kit  
General Description  
Features  
o Designed to Meet VRM 9.0 Mechanical and  
The MAX5037 evaluation (EV) kit is a fully assembled  
and tested VRM power-supply evaluation kit. The EV kit  
module can be inserted directly into the VRM daughter  
board AMP connector (1364125-1 or equivalent) on  
Electrical Specifications  
o Two-Phase Power Conversion  
®
Pentium 4 processor motherboards. The input voltage  
o 5V or 12V Input Operation (Design Optimized for  
range is either 4.75V to 5.5V or 8V to 13.2V. The EV kit  
design is optimized for the best performance at 12V  
input and 1.75V output voltage settings. The output is  
programmable from 1.1V to 1.85V through VID input in  
compliance with Intel’s VRM 9.0 specification. Up to 52A  
load current is possible from dual-phase conversion.  
High-power density and simple assembly is achieved  
due to a lower component count using the MAX5037.  
12V Input)  
o Output Voltage Programmable from 1.1V to 1.85V  
in 25mV Step-Through VID Input  
o VRM 9.0-Compliant Integrated 5-Bit DAC  
o 52A Output Current  
o Adaptive Voltage Positioning for Optimized  
Transient Response  
Warning  
o Average Current-Mode Control for Superior  
The MAX5037 EV kit is designed to operate at high cur-  
rents, and some of the components operate at high  
temperatures. Avoid touching the components. The  
evaluation board is not provided with a fuse. Use a  
controlled current source to power up the board.  
Under severe fault conditions, this EV kit may dissipate  
a large amount of power. To avoid possible personal  
injury, operate this kit with care.  
Current Sharing  
o Current-Sharing Accuracy Within 5% Between  
Parallel Channels  
o Up to 95% Efficiency  
o 500kHz Effective Switching Frequency  
(Two Phases)  
Pentium is a registered trademark of Intel Corp.  
o Output Overload Protection  
o Output Overvoltage Crowbar Protection  
o Internal Undervoltage Lockout and Startup Circuit  
o Excellent Line-and-Load Transient Response  
o Phase Failure Detector
