MAXM17536
4.5V to 60V, 4A 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 enables cooler, smaller, and simpler power supply
solutions. The MAXM17536 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 4A continuous output
current with excellent line and load regulation over an
output-voltage range of 0.9V to 12V. 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.
and Time-to-Market
• Integrated Synchronous Step-Down DC-DC
Converter
• Integrated Inductor
• Integrated FETs
• Integrated Compensation Components
● Saves Board Space in Space-Constrained
Applications
• Complete Integrated Step-Down Power Supply
in a Single Package
• Small Profile, 9mm x 15mm x 4.32mm SiP Package
• Simplified PCB Design with Minimal External BOM
The device can be operated in the pulse-width modulation

conduction mode (DCM) control schemes.
Components
● Offers Flexibility for Power-Design Optimization
• Wide Input-Voltage Range from 4.5V to 60V
• Output-Voltage Adjustable Range from 0.9V to 12V
The MAXM17536 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.
