EVALUATION KIT AVAILABLE
4A, 2.4V to 5.5V Input,
High-Efficiency Power Module
General Description
The MAXM17514 is a fixed-frequency, step-down power
module in a thermally-efficient system-in-package
(SiP) package that operates from a 2.4V to 5.5V input
supply voltage and supports output currents up to
4A. The device includes switch-mode power-supply
controller, dual nMOSFET power switches, a fully shielded
inductor, as well as compensation components. The device
supports 0.75V to 3.6V programmable output voltage.
The high level of integration significantly reduces design
complexity, manufacturing risks, and offers a true plug-
and-play power-supply solution, reducing the time to
market.
The MAXM17514 is available in a thermally enhanced,
compact 28-pin, 10mm x 6.5mm x 2.8mm SiP package
and can operate over the -40°C to +125°C industrial
temperature range.

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.
