MAXM17574中文资料4.5V to 60V, 3A High-Efficiency, DC-DC Step-Down Power Module with Integrated Inductor数据手册ADI规格书

描述 Description

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM17574 is an easy-to-use power module that combines a synchronous step-down DC-DC converter, fully shielded inductor, and 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, delivers up to 3A continuous output current, and has excellent line and load regulation over an output-voltage range of 0.9V to 15V. 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 pulse-width modulation (PWM) or discontinuous conduction mode (DCM).

The MAXM17574 is available in a low-profile, highly thermal-emissive, compact, 33-pin, 9mm x 15mm x 2.92mm SiP package that reduces power dissipation in the package and enhances efficiency. The feedback voltage-regulation accuracy over -40°C to +125°C is ±0.9%. The package is easily soldered onto a printed circuit board and suitable for automated circuit board assembly.
