MAXM17900EVKIT

Description

Create a design and simulate using EE-Sim^® tools:

The MAXM17900 evaluation kit (EV kit) is a demonstration circuit of the MAXM17900 ultra-small, high efficiency, current mode, synchronous step-down DC-DC switching power module. The EV kit operates over an input-voltage of 10V to 24V 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-by-cycle 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 uSLIC™ package MAXM17900 module installed, and is rated to operate over the full industrial/automotive -40°C to +125°C temperature range. For full specifications, features and benefits of the IC, refer to the MAXM17900 data sheet.
