Surprised there isn’t a representative circuit diagram in the data sheets Tim. Was basing my comment on the LDDs running in parallel based on this post and nearby thread context:

BB code is On. A Schottky makes sense.
The low side diodes would be redundant and not needed. Sao Paulo, Brazil Posts: Safety depends if the LDD is also measuring switch or inductor current and not just LED cathode current it’s possible.

Aside from oscilloscope to monitor LF ripple characteristics on the output once the drivers were wired in ldc-1000hw, would dinmable be enough to watch the amperage on a multimeter to make sure the current didn’t start fluctuating to values higher than the max emitter spec?
