Product Details

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler powersupply solutions. The MAXM17537EVKIT# 15V-output evaluation kit (EV kit) is a demonstration circuit of the MAXM17537 60V, 3A high-efficiency, current-mode, synchronous step-down DC-DC switching power module. The EV kit operates over a wide input-voltage of 19V to 60V and provides up to 3A load current with a 15V-output voltage. The EV kit is programmed to switch at a frequency of 700kHz. The module is simple to use and easily configurable with minimal external components. It features cycle-by-cycle peak current-limit protection, undervoltage lockout (EN/UVLO), and thermal shutdown.

The EV kit includes the compact, 29-pin, 15mm x 9mm x 4.32mm SiP package MAXM17537 module installed and is rated to operate over the full industrial -40°C to 125°C temperature range.

The MAXM17537 module data sheet provides a complete description of the part that should be read in conjunction with this data sheet prior to operating the EV kit. For full module features, benefits and parameters, refer to the MAXM17537 data sheet.
