MAXM17514
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.
