Design Guide ICLSx Series

The LED demo board design combines a conventional low cost single stage PFC and flyback converter topology. This type of design is particularly suitable for retrofit lighting applications. The ICLSx series LEDSet system driver IC is a current-controlled pulse width modulator together with a CoolMOS™ power switch on board. Special efforts have been made to compensate temperature dependency in order to achieve a very high accuracy of switching frequency. Short output and floating load protection are implemented by controlling the feedback voltage. Depending on the error case, the IC works in Auto Restart (ARM) or Floating Load Protection (FLPM) mode. For constant power, Infineon Technologies patented functionality is integrated.
