MAX17691BEVKIT#

MAX17691BEVKIT# is a MAX17691B evaluation kit (EV kit) that provides a proven design to evaluate the performance of the MAX17691B IC. This fully assembled and tested circuit evaluates the MAX17691B, the No-Opto Flyback Converter with an integrated 76V nMOSFET, available in a 12-pin TDFN package with an exposed pad. The MAX17691B EV kit output is configured for an isolated +5V and provides up to 1.5A of output current over an 18V to 36V input range. The device has 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 opto-coupler for the isolated output-voltage sensing.
