40W Reference Design with CDM10V Isolated 0-10V Dimming Interface
The 40W LED driver with isolated 0 – 10 V dimming interface is available to quickly assess the performance and assess the bill of materials. The demoboard supports universal input voltage from 90-305 VAC, a wide output voltage range from 15 - 45 VDC and isolated 0-10 V dimming for LED lighting applications. The design is using the Infineon components XDP™ ICL8105 digital flyback controller, the CDM10V as solution for isolated 0-10V dimming, and 800V CoolMOS™ CE

Summary of Features:
- Single-stage flyback with power factor correction (PFC) and high-precision primary side-controlled constant current output. Excellent current accuracy of typ +/-3% across wide line/load to maintain aconstant light output
- The ICL8105 supports isolated 0-10 V dimming without the need for extra ICs. Extended dimming is supported down to 1% of the nominal load. Besides, the dimming curve is adjustable (linear / eye adapted).Configurable voltage levels ensure that min and max current can always be achieved, making the application robust against dimmer & component tolerances
- The CDM10V is used to transmit analog voltage based signals from a 0-10 V dimmer to the dimming input of the ICL8105. The CDM10V thereby drives an external opto-coupler with a current based PWM signal.
