EVALUATION KIT AVAILABLE
4.5V to 36V, 1A Himalaya uSLIC
Step-Down Power Module
General Description
The Himalaya series of voltage regulator ICs and power
modules enable cooler, smaller, and simpler power supply
solutions. The MAXM17630/MAXM17631/MAXM17632
are a family of high-efficiency, synchronous step-down
DC-DC modules with integrated controller, MOSFETs,
compensation components and inductor that operate
over a wide input-voltage range. The modules operate
from 4.5V to 36V and deliver up to 1A output current.
The MAXM17630 and MAXM17631 are fixed 3.3V and
5V output modules, respectively. The MAXM17632 is an
adjustable output (0.9V to 12V) module. The modules sig-
nificantly reduce design complexity, manufacturing risks,
and offer a true plug-and-play power-supply solution,
reducing time-to-market. Built-in compensation across
the output-voltage range eliminates the need for external
compensation components.
These modules feature peak-current-mode control
architecture. The modules can be operated in pulse-
width modulation (PWM), or pulse-frequency modu-
lation (PFM), or discontinuous-conduction mode
(DCM) to enable high efficiency under light-load
conditions.
The feedback-voltage regulation accuracy over -40°C
to +125°C for the module family is ±1.2%. These power
modules are available in a low profile, compact 16-pin,
3mm x 3mm x 1.75mm, uSLIC™ package. Simulation
Models are available.

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.
