The MAX5038/MAX5041 dual-phase, PWM controllers

provide high-output-current capability in a compact

package with a minimum number of external compo-

nents. The MAX5038/MAX5041 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

op timum tra ns ie nt re s p ons e . An inte rna l re g ula tor

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

va lue s . This a c c ommod a te s the us e of PC b oa rd -

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

♦ Integrated 4A Gate Drivers

The MAX5038/MAX5041 a ls o fe a ture a c loc k inp ut

(CLKIN) for synchronization to an external clock, and a

clock output (CLKOUT) with programmable phase delay

(relative to CLKIN) for paralleling multiple phases. The

MAX5038 offers a variety of factory-trimmed preset output

voltages (see Selector Guide) and the MAX5041 offers an

adjustable output voltage from +1.0V to +3.3V.

♦ Selectable Fixed Frequency 250kHz or 500kHz Per

Phase (Up to 1MHz for 2 Phases)

♦ Fixed (MAX5038) or Adjustable (MAX5041) Output

Voltages

♦ 0.5% Accurate Reference (MAX5041B)

The MAX5038/MAX5041 operate over the extended

industrial temperature range (-40°C to +85°C) and are

a va ila b le in a 28-p in SSOP p a c ka g e . Re fe r to the

MAX5037 data sheet for a VRM 9.0-compatible, VID-

controlled output voltage controller in a 44-pin MQFP or

QFN package.

♦ External Frequency Synchronization from 125kHz

to 600kHz

♦ Internal PLL with Clock Output for Paralleling

Multiple DC-DC Converters

♦ Thermal Protection
