It has a non- rms rms dimmed output current set-point of 830 mA and an output power limitation set-point of 35 W. The 35 W reference design is ready to be tested out of the box, as shown in Figure 1. There is no need for any pre-programming by the user, as the XDPL8210 chip on the reference board has already been burned with the first full configuration set of working parameters. A simple test set-up can be done by connecting the boards AC input (L live, N neutral) to the AC source, the boards output to the LEDs (+, -) and 0 to 10 V dimming input to the DC source, based on Figure 1. Attention: Lethal voltages are present on this reference design. Do not operate the board unless you are trained to handle high voltage circuits. Do not leave this board unattended when it is powered up. 0 to 10 V - dimming + - Output to LEDs + L AC input N XDPL8210 parameter configuration connector X2 Figure 1 XDPL8210 CDM10VD 35 W reference design Engineering Report 2 of 26 V 1.1 2021-07-01
