Product Details

The Himalaya series of voltage regulator ICs and Power Modules enable cooler, smaller, and simpler power supply solutions. The MAXM17761 is an easy-to-use power module that combines a synchronous step down DC-DC converter with integrated FETs ,a fully shielded inductor, and the compensation components into a low-profile, thermally-efficient, system-in-package (SiP). The device operates over a wide input voltage range of 4.5V to 76V and delivers up to 1A continuous output current with excellent line and load regulation over an output voltage range of 0.8V to 5V. 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.

The device offers resistor programmable switching frequency, active-low RESET output voltage monitoring, adjustable input undervoltage lockout and programmable soft-start. The device also features robust overload protection and a thermal shutdown function.

The MAXM17761 is available in a low-profile, highly thermal-emissive, compact, 28-pin 6.5mm x 10mm x 2.92mm SiP package that reduces power dissipation in the package and enhances efficiency. The package is easily soldered onto a printed circuit board and is suitable for automated circuit board assembly. The device can operate over the full industrial temperature range from -40°C to +125°C.
