MAXM17503
EVALUATION KIT AVAILABLE
4.5V to 60V, 2.5A High-Efficiency, DC-DC
Step-Down Power Module with Integrated Inductor
General Description
The Himalaya series of voltage regulator ICs and Power
Modules enable cooler, smaller and simpler power supply
solutions. The MAXM17503 is an easy-to-use, step-down
power module that combines a switching power supply
controller, dual n-channel MOSFET power switches, fully
shielded inductor, and the compensation components
in a low-profile, thermally-efficient, system-in-package
(SiP). The device operates over a wide input voltage
range of 4.5V to 60V and delivers up to 2.5A continuous
output current with excellent line and load regulation
over an output voltage range of 0.9V to 12V. The device
only requires five external components to complete
the total power solution. The high level of integration
significantly reduces design complexity, manufacturing
risks, and offers a true plug-and-play power supply solution,
reducing time-to-market.
The device can be operated in the pulse-width modulation
(PWM), pulse-frequency modulation (PFM), or discontinuous
conduction mode (DCM) control schemes.
The MAXM17503 is available in a low-profile, highly
thermal-emissive, compact, 29-pin 9mm x 15mm x
2.8mm SiP package that reduces power dissipation in
the package and enhances efficiency. The package is
easily soldered onto a printed circuit board and suit-
able for automated circuit board assembly. The device
can operate over the industrial temperature range from
-40°C to +125°C.
