Analog Devices / Maxim Integrated MAXM17900EVKIT Power Module Evaluation Kit

Analog Devices MAXM17900EVKIT Power Module Evaluation Kit is a demonstration circuit of the MAXM17900 ultra-small, high efficiency, current mode, synchronous step-down DC-DC switching power module. The evaluation kit operates over an input voltage of 10V to 21V and provides up to 100mA load current with a 5V output voltage. The evaluation kit is programmed to switch at a frequency of 600kHz. The module is simple to use and easily configurable with minimal external components. The kit features cycle-by-cycle peak current-limit protection under voltage lockout (EN/UVLO) and thermal shutdown. The Analog Devices MAXM17900EVKIT comes with the compact 10-pin 2.6mm x 3mm x 1.5mm micro-SLIC package MAXM17900 module installed and is rated to operate over the full industrial/automotive -40°C to +125°C temperature range.
