Dual-Phase, Parallelable, Average-Current-Mode

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.
