VRM 9.0, Dual-Phase, Parallelable,  
Average Current-Mode Controller  
General Description  
Features  
The MAX5037 dual-phase, PWM controller provides  
high-output-current capability in a compact package  
with a minimum number of external components. The  
MAX5037 utilizes a dual-phase, average current-mode  
♦ +4.75V to +5.5V or +8V to +28V Input Voltage  
Range  
♦ Up to 60A Output Current  
control that enables optimal use of low R  
DS(ON)  
♦ Internal Voltage Regulator for a +12V or +24V  
MOSFETs, eliminating the need for external heatsinks  
even when delivering high output currents.  
Power Bus  
♦ Internal 5-Bit DAC VID Control (VRM 9.0  
Differential sensing enables accurate control of the  
output voltage, while adaptive voltage positioning  
provides optimum transient response. An internal regula-  
tor enables operation with either +5V or +12V input volt-  
age without the need for additional voltage sources. The  
high switching frequency, up to 500kHz per phase, and  
dual-phase operation allow the use of low output induc-  
tor values and input capacitor values. This accommo-  
dates the use of PC board-embedded planar magnetics  
achieving superior reliability, current sharing, thermal  
management, compact size, and low system cost.  
Compliant, 0.8% Accuracy)  
♦ Programmable Adaptive Output Voltage  
Positioning  
♦ True Differential Remote Output Sensing  
♦ Out-Of-Phase Controllers Reduce Input  
Capacitance Requirement and Distribute Power  
Dissipation  
♦ Average Current-Mode Control  
The MAX5037 also features a clock input (CLKIN) for syn-  
chronization to an external clock, and a clock output  
(CLKOUT) with programmable phase delay (relative to  
CLKIN) for paralleling multiple phases.  
Superior Current Sharing Between Individual  
Phases and Paralleled Modules  
Accurate Current Limit Eliminates MOSFET and  
Inductor Derating  
The MAX5037 operates over the extended industrial  
temperature range (-40°C to +85°C) and is available in  
44-pin MQFP or thin QFN packages. Refer to the  
MAX5038/MAX5041 data sheet for either a fixed output  
voltage controller or an adjustable output voltage con-  
troller in a 28-pin SSOP package.  
♦ Integrated High-Output-Current Gate Drivers  
♦ Selectable Fixed Frequency 250kHz or 500kHz Per  
Phase (Up to 1MHz for 2 Phases)  
♦ External Frequency Synchronization from 125kHz  
to 600kHz  
Applications  
♦ Internal PLL with Clock Output for Paralleling  
Servers and Workstations  
Multiple DC-DC Converters  
Point-Of-Load High-Current/High-Density  
Telecom DC-DC Regulators  
♦ Power-Good Output  
♦ Phase Failure Detector  
Networking Systems  
Large-Memory Arrays  
RAID Systems  
♦ Overvoltage and Thermal Protection  
♦ 44-Pin MQFP or QFN Packages  
High-End Desktop Computers
