6A, 2.4V to 5.5V Input, High-Efficiency Power Module

Highly Integrated DC-DC Power Module Enables Ease of Design and Small-Solution Footprint

Product Details

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17516 is a fixed-frequency, step-down power module in a thermally-efficient system-in-package (SiP) package that operates from a 2.4V to 5.5V input supply voltage and supports output currents up to 6A. The device includes a switch-mode power-supply controller, dual n-channel MOSFET power switches, a fully-shielded inductor, as well as compensation components. The device supports 0.75V to 1.8V programmable output voltage. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true plug-and-play power-supply solution, reducing the time to market.

The MAXM17516 is available in a thermally-enhanced, compact 28-pin, 10mm x 6.5mm x 2.8mm SiP and can operate over the -40°C to +125°C industrial temperature range.

Description

The MAXM17516 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the typical 6A application circuit of the MAXM17516. The MAXM17516 is a fixed-frequency, integrated inductor, step-down power module for low-voltage, low-power applications.

The EV kit provides a 1.5V output voltage from a 2.4V to 5.5V input range and delivers up to 6A output current while achieving greater than 90.6% efficiency. The EV kit operates at 1MHz switching frequency and has superior line and load-transient response. The EV kit also allows the evaluation of other adjustable output voltages from 0.75V to 1.8V by changing resistors R1 and R2.
