MAXM1750x Power Module

Maxim Intergrated's MAXM1750x highly integrated DC-DC power module enables ease of design and a small-solution footprint

Image of Maxim Integrated's MAXM1750 Power ModuleMaxim's Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM1750x 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 4.5 V to 60 V and delivers up to 1.7 A,  2.5 A, or 3.5 A continuous output current with excellent line and load regulation over an output voltage range of 0.9 V to 12 V. The device only requires five external components to complete the total power solution. 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.

Maxim's MAXM170x can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes. The MAXM1750x is available in a low-profile, highly thermal- emissive, compact, 29-pin, 9 mm x 15 mm x 2.8 mm SiP package that reduces power dissipation in the package and enhances efficiency. The package is easily soldered onto a printed circuit board (PCB) and is suitable for automated circuit board assembly. The device can operate over the industrial temperature range from -40°C to 125°C.
