The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller and simpler power-supply solutions. The MAXM17504 is an easy-to-use, Himalaya 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 60V and delivers up to 3.5A continuous output current with excellent line and load regulation over an output voltage range of 0.9V to 12V. 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 can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes.

The MAXM17504 is available in a low-profile, highly thermal- emissive, compact, 29-pin 9mm x 15mm x 2.8mm 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. The device can operate over a wide industrial temperature range from -40°C to +125°C.

Product Detail

The MAXM17504 evaluation kit (EV kit) is a demonstration circuit of the MAXM17504 high-voltage, high-efficiency, current-mode scheme, synchronous step-down DC-DC switching power module. The MAXM17504 EV kit is designed for 5V output and delivers up to 3.5A load current from a wide input voltage range of 11V to 60V. The EV kit switches at an optimal 500kHz switching frequency to allow the use of small component sizes that help minimize solution size while maintaining high performance. The EV kit provides a precision-enable input, an open-drain active-low RESET output signal, and external frequency synchronization to provide a simple and reliable startup sequence and eliminate beat frequency between regulators. 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 MAXM17504 data sheet provides a complete description of the part that should be read in conjunction with this evaluation kit data sheet prior to modifying the demo circuit.
