MAXM17537
4.5V to 60V, 3A High-Efficiency, DC-DC Step-Down
SiP Power Module with Integrated Inductor
General Description
Benefits and Features
● Reduces Design Complexity, Manufacturing Risks,
The Himalaya series of voltage regulator ICs and power
modules enable cooler, smaller, and simpler power supply
solutions. The MAXM17537 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 3A continuous output cur-
rent with excellent line and load regulation over an output-
voltage range of 8V to 24V. The high level of integration
significantly reduces design complexity and manufactur-
ing risks, and offers a true plug-and-play power supply
solution, reducing time to market.

Synchronization (100kHz to 2.2MHz)
The device can be operated in the pulse-width modulation
(PWM), pulse-frequency modulation (PFM), or discontinu-
ous-conduction mode (DCM) control schemes.
The MAXM17537 is available in a low-profile, highly
thermal-emissive, compact, 29-pin, 9mm x 15mm x
4.32mm SiP package that reduces power dissipation in
the package and enhances efficiency. The package is
easily soldered onto a printed circuit board and suitable
for automated circuit board assembly.
