OPT8241-CDK-EVM: Possible design error in LED Driver

Julian Wagner

Part Number: OPT8241-CDK-EVM

Hi,

please correct me if I am wrong but I think there is a mistake in the OPT8241-CDK IB design (REV2P0V1). In my opinion there is a connection missing in the LEDs constant current driver (sheet 7/9). I added what I believe is the missing connection in black in the picture below.

Best regards,

Hi Julian,

There are multiple ways of connecting nets in the schematic. Connecting with wires is one way. Another way is to give the 2 nets the same name. This schematic has both the nets named as "SW". Hence, they are already shorted.

If you intend to use the LEDs on the CDK, attached PDF has instructions.

Regards,
Subhash
