General Desc ription
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
of low R
DS(ON)
MOSFETs, eliminating the need for exter-
nal heatsinks even when delivering high output currents.
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.
The MAX5038/MAX5041 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
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.
The MAX5038/MAX5041 operate over the extended
industrial temperature range (-40°C to +85°C) and are
available in a 28-pin SSOP package. Refer to the
MAX5037 data sheet for a VRM 9.0-compatible, VID-
controlled output voltage controller in a 44-pin MQFP or
QFN package.
