Evaluation Kit for the MAX17597 Flyback Configuration

Please check latest availability status for a specific part variant.


The MAX17597 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates an isolated 20W flyback DC-DC converter. The circuit uses the device’s peak-current-mode controller in a 16-pin TQFN package with an exposed pad. The EV kit demonstrates the IC’s cycle-by-cycle current-limit, soft-start, and EN/UVLO features.

The EV kit circuit output is configured for an isolated 24V and provides up to 833mA of output current. The EV kit is configured to operate at a 200kHz switching frequency. An optocoupler, along with the transformer, provides galvanic isolation between input and output, up to 1500VRMS.
