The MAX17498B evaluation kit (EV kit) is a fully assembled and tested circuit board that contains an isolated 7W flyback DC-DC converter. The circuit uses the MAX17498B current-mode, fixed-frequency flyback converter 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 UVLO features.
The EV kit circuit output is configured for an isolated +5V and provides up to 1.5A of current. Low cost and high efficiency up to 88% are achieved using a flyback DC-DC converter topology operating at a fixed 500kHz switching frequency. The surface-mount transformer provides up to +1500V galvanic isolation at the output.
The EV kit operates from a +18V to +36V power supply capable of providing up to 1A.
