Description

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller and simpler power supply solutions. The MAXM17546 is an easy-to-use, step-down power module that combines a switching power supply controller, dual n-channel MOSFET power switches, fully shielded inductor, and the compensation components in a low-profile, thermally-efficient system-in-package (SiP).

The device operates over a wide input voltage range of 4.5V to 42V and delivers up to 5A continuous output current with excellent line and load regulation over an output-voltage range of 0.9V to 12V. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true plug-and-play power supply solution, reducing time-to-market.

The device can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes.

The MAXM17546 is available in a low-profile, highly thermal-emissive, compact, 29-pin, 9mm x 15mm x 4.32mm SiP package that reduces power dissipation in the package and enhances efficiency. The package is easily soldered onto a printed circuit board and suitable for automated circuit board assembly.
