Analog Devices MAX17691A | Demoboard MAX17691AEVKIT

Description

The MAX17691A evaluation kit (EV kit) provides a proven design to evaluate the performance of MAX17691A IC. This fully assembled and tested circuit is implemented using the MAX17691A, the No-Opto Flyback converter with an integrated 76V nMOSFET, available in a 12-pin TDFN package with an exposed pad. The IC data sheet provides a complete description of the part and should be read in conjunction with this EV kit data sheet prior to operating the EV kit.The MAX17691A EV kit output is configured for an isolated +5V and provides up to 1.5A of output current over a 18V to 36V input range. The device switches at a 150kHz switching frequency. The EV kit regulates the output voltage within ±5% over the line, load, and temperature by sensing the output voltage on the primary side. The converter does not need an optocoupler for the isolated output voltage sensing.
