4.5V to 60V, 1.5A High-Efficiency, DC-DC Step-Down Power Module with Integrated Inductor

Description

Create a design and simulate using EE-Sim^® tools:

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17575 is an easy-to-use power module that combines a synchronous step-down DC-DC converter, a fully shielded inductor, and 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 60V, delivers up to 1.5A continuous output current and has excellent line and load regulation over an output-voltage range of 0.9V to 12V. 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 MAXM17575 offers resistor-programmable switching frequency, active-low RESET output-voltage monitoring, adjustable input undervoltage lockout, and programmable soft-start. The device also features hiccup-mode overload protection, and thermal shutdown function.

The MAXM17575 is available in a low-profile, highly thermal-emissive, compact, 28-pin 6.5mm × 10mm × 2.92mm SiP package, which reduces power dissipation 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 industrial temperature range from -40°C to +125°C.
