Additional Details

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17502 is a high-voltage, step-down power module in a family of pin-to-pin compatible modules with built-in thermally efficient system-in-packages (SiPs). The device includes a switch mode power supply controller, MOSFETs, an inductor, as well as the compensation components. The device operates from a 4.5V to 60V input supply voltage and supports adjustable output voltage from 0.9V to 5.0V with an output current of 1A. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true plug-and-play power supply solution to reduce time to market.

The pin-to-pin compatibility within this family of modules allows design flexibility as the design requirements change. For sequencing purpose, the device features adjustable soft-start time, programmable EN/UVLO threshold, and a power-good indicator (Active-Low RESET pin).

The MAXM17502 is available in a thermally enhanced, compact, 28-pin, 6.5mm x 10mm x 2.8mm SiP package. It operates over the -40°C to +125°C industrial temperature range.

Product Detail

The MAXM17502 evaluation kit (EV kit) is a demonstration circuit of the MAXM17502 high-voltage, high-efficiency, current mode, synchronous step-down DC-DC switching power module. The EV kit is designed to provide 5V with up to 1A load of current from a wide input-voltage range of 12V to 60V. The EV kit switches at an optimal 540kHz switching frequency to allow for small component and solution sizes while maintaining high performance. The EV kit provides a precision-enable input and an open-drain active-low RESET output signal to provide a simple and reliable startup sequence. The EV kit also includes optional component footprints to program different output voltages, an adjustable input undervoltage-lockout, and a soft-start time to control inrush current during startup. The MAXM17502 module data sheet provides a complete description of the part and should be read in conjunction with this evaluation kit data sheet prior to modifying the demo circuit.
