Product Details

The MAX17692AEVKIT# evaluation kit (EV kit) provides a proven design to evaluate the performance of the MAX17692A IC. This fully assembled and tested circuit is implemented using the MAX17692A, 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 MAX17692AEVKIT# EV kit output is configured for an isolated +5V and provides up to 0.65A of output current over an 18V to 36V input range. The device switches at a 145kHz switching frequency. The EV kit regulates the output voltage within ±5% over 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.

Applications

  • IGBT Gate Drive Supplies
  • Industrial and Telecom Applications
  • Isolated Power Supplies
  • PLC I/O Modules
