4.5V to 36V, 2A Himalaya uSLIC
Step-Down Power Modules
General Description
The Himalaya series of voltage regulator ICs and power
modules enable cooler, smaller, and simpler power
supply solutions. The MAXM17633, MAXM17634, and
MAXM17635 are a family of high-frequency synchronous
step-down DC-DC converter modules with integrated con-
troller, MOSFETs, compensation components, and induc-
tor, that operate over a wide input voltage range. The mod-
ules operate from 4.5V to 36V input and deliver up to 2A out-
put current. MAXM17633 and MAXM17634 are fixed 3.3V
and 5V output modules, respectively. The MAXM17635
is an adjustable-output voltage (0.9V to 12V) module.
The modules significantly reduce design complexity,
manufacturing risks, and offer a true plug-and-play power
supply solution, reducing time to market.
The MAXM17633/MAXM17634/MAXM17635 modules
employ peak-current-mode control architecture. To reduce
input inrush current, the devices offer a programmable
soft-start time.
The MAXM17633/MAXM17634/MAXM17635 modules are
available in a low profile, compact 24-pin, 4mm x 4mm x
1.75mm, uSLIC™ package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Note 1: Junction temperature greater than +125°C degrades operating lifetimes.
Note 2: Package thermal resistance is measured on an evaluation board with natural convection.
