Product Details

The MAXM17532 evaluation kit (EV kit) is a demonstration circuit of the MAXM17532 42V,100mA ultra-small, high efficiency, current mode, synchronous step-down DC-DC switching power module. The EV kit operates over a wide input-voltage of 10V to 42V and provides up to 100mA load current with a 5V output voltage. The EV kit is programmed to switch at a frequency of 600kHz. The module is simple to use and easily configurable with minimal external components. It features cycle-bycycle peak current-limit protection, undervoltage lockout (EN/UVLO), and thermal shutdown.

The EV kit comes with the compact 10-pin 2.6mm x 3mm x 1.5mm µSLIC™ package MAXM17532 module installed, and is rated to operate over the full industrial/ automotive -40°C to +125°C temperature range.
