Controllers  
General Description  
Features  
The MAX5038A/MAX5041A dual-phase, PWM controllers  
provide high-output-current capability in a compact  
package with a minimum number of external compo-  
nents. The MAX5038A/MAX5041A utilize a dual-phase,  
average-current-mode control that enables optimal use  
ꢀ +4.75V to +5.5V or +8V to +28V Input Voltage  
Range  
ꢀ Up to 60A Output Current  
ꢀ Internal Voltage Regulator for a +12V or +24V  
of low R  
MOSFETs, eliminating the need for exter-  
DS(ON)  
Power Bus  
nal heatsinks even when delivering high output currents.  
ꢀ True Differential Remote Output Sensing  
Differential sensing enables accurate control of the out-  
put voltage, while adaptive voltage positioning provides  
optimum transient response. An internal regulator  
enables operation with input voltage ranges of +4.75V to  
+5.5V or +8V to +28V. The high switching frequency, up  
to 500kHz per phase, and dual-phase operation allow  
the use of low-output inductor values and input capacitor  
values. This accommodates the use of PC board-  
embedded planar magnetics achieving superior reliabili-  
ty, current sharing, thermal management, compact size,  
and low system cost.  
ꢀ Two Out-Of-Phase Controllers Reduce Input  
Capacitance Requirement and Distribute Power  
Dissipation  
ꢀ Average-Current-Mode Control  
Superior Current Sharing Between Individual  
Phases and Paralleled Modules  
Accurate Current Limit Eliminates MOSFET and  
Inductor Derating  
ꢀ Limits Reverse-Current Sinking in Paralleled  
The MAX5038A/MAX5041A also feature a clock input  
(CLKIN) for synchronization to an external clock, and a  
clock output (CLKOUT) with programmable phase delay  
(relative to CLKIN) for paralleling multiple phases. The  
MAX5038A/MAX5041A also limit the reverse current in  
case the bus voltage becomes higher than the regulat-  
ed output voltage. The MAX5038A offers a variety of fac-  
tory-trimmed preset output voltages (see Selector Guide)  
and the MAX5041A offers an adjustable output voltage  
between +1.0V to +3.3V.  
Modules  
ꢀ Integrated 4A Gate Drivers  
ꢀ Selectable Fixed Frequency 250kHz or 500kHz per  
Phase (Up to 1MHz for Two Phases)  
ꢀ Fixed (MAX5038A) or Adjustable (MAX5041A)  
Output Voltages  
ꢀ External Frequency Synchronization from 125kHz  
to 600kHz  
The MAX5038A/MAX5041A operate over the extended  
temperature range (-40°C to +85°C) and are available  
in a 28-pin SSOP package. Refer to the MAX5037A and  
MAX5065/MAX5067 data sheets for a VRM 9.0/VRM 9.1-  
compatible, VID-controlled, adjustable output voltage  
controller in a 44-pin MQFP/thin QFN or 28-pin SSOP  
package.
