Beschreibung

The MAX17596 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates an isolated 20W fly-back 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 the input and output, up to 1500VRMS.
