MAXM17505
4.5V to 60V, 1.7A High-Efficiency, DC-DC Step-
Down Power Module with Integrated Inductor
●
Saves Board Space in Space-Constrained
Applications
General Description
The Himalaya series of voltage regulator ICs, power mod-
ules, and chargers enable cooler, smaller, and simpler
power supply solutions. The MAXM17505 is an easy-to-
use, Himalaya 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 deliv-
ers up to 1.7A 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.

discontinuous conduction mode (DCM) control schemes.
• RESET/Output-Voltage Monitoring
• Wide Industrial Ambient Operating Temperature
Range (-40°C to +125°C)/Junction Temperature
Range (-40°C to +150°C)
The MAXM17505 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 suitable
for automated circuit board assembly. The device can
operate over a wide industrial temperature range from
-40°C to +125°C.
