4A, 2.4V to 5.5V Input, High-Efficiency Power Module

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 n-channel MOSFET 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.
