MAX5037EMH
4.75 to 5.5 V or 8 to 28 V, VRM 9.0, dual-phase, parallelable, average current-mode controller
General DescriptionThe 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
control that enables optimal use of low RDS(ON)
MOSFETs, eliminating the need for external heatsinks
even when delivering high output currents.
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.
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.
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.
