Product Details

The MAX5099 evaluation kit (EV kit) is an assembled and tested PCB that contains all the components necessary to evaluate the MAX5099 IC. The MAX5099 is a dual-output, synchronous step-down DC-DC converter. The EV kit is powered from a DC supply providing 5.2V to 19V and up to 5A. The EV kit can also be reconfigured for an input range between 4.5V to 5.5V. The EV kit is designed to withstand a load-dump condition up to 80V.

The MAX5099 EV kit can deliver 5V at 2A from the first step-down DC-DC converter output and 3.3V at up to 1A from the second step-down DC-DC converter output. The MAX5099 switching frequency is set to 1.9MHz, and the two outputs switch 180° out-of-phase with respect to each other. A SYNC input facilitates external frequency synchronization of the EV kit. The 5V converter switching frequency is configurable to half that of the 3.3V converter. The EV kit includes a shutdown feature, converter power-up sequencing, and individual converter enables.
