Description

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.
