MAX16841EVKIT#: 248 ~ 427mA @ 23V Max, 85 ~ 264Vac

Summary

The MAX16841 evaluation kit (EV kit) demonstrates the MAX16841 LED driver IC used for offline LED lighting applications. The EV kit is configured as a flyback topology to drive 6 to 8 LEDs from a universal AC input supply. The IC is designed for standard offline applications. The typical input power at 230V AC input is 11.7W.

The EV kit is designed to pass EM55015 Class B specifications and EN6100-3-2 for harmonic currents. The EV kit is dimmable with most of the leading- and trailing-edge dimmers.

The EV kit circuit is configured in a flyback topology and provides up to 10W of output power for a string of 8 series LEDs connected at the LED+ and LED- test points. The converter switching frequency is set at 70kHz. The EV kit circuit operates from an AC supply voltage of 90VRMS to 265VRMS. The EV kit is designed on a proven 2oz copper, two-layer small PCB footprint design. The EV kit is optimized for operation in the 180VRMS to 265VRMS range.
