MAXM15462
MAXM15462
EVALUATION KIT AVAILABLE
4.5V to 42V, 300mA 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 MAXM15462 is a high-efficiency,
synchronous step-down DC-DC module with integrated
controller, MOSFETs, compensation components, and
inductor that operates over a wide input-voltage range.
The module operates from 4.5V to 42V input and delivers
up to 300mA output current over a programmable output
voltage from 0.9V to 5V. The module significantly reduces
design complexity, manufacturing risks, and offers a true
plug and play power/supply solution, reducing time-to-
market.
The MAXM15462 employs peak-current-mode control
architecture. To reduce input inrush current, the device
offers a fixed 4.1ms soft-start time.
The MAXM15462 module is available in a low profile, com-
pact 10-pin, 2.6mm × 3mm × 1.5mm, uSLIC™ package.

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.
