All times are GMT Was basing my comment on the LDDs running in parallel based on this post and nearby thread context: A Schottky makes sense.

Turns out, I’m actually having trouble finding if the hw can be wired in parallel.


For full functionality of this site it is necessary to enable JavaScript. Aside from oscilloscope to monitor LF ripple characteristics on the output once the drivers were wired in parallel, would it be enough to watch the amperage on a dimmanle to make sure the current didn’t start fluctuating to values higher than the max emitter spec?


Box Type – Enclosed. Three low Vf schottky diodes of the appropriate rating would be ideal. Sao Paulo, Brazil Posts: Are you thinking of the LDD in the sense of a straightforward buck converter with a switch and an inductor?

Mean Well LDDHW

The low side diodes would be redundant and not needed. These diodes will be heating as well 0.

Ahh, looks like each output requires a forward-biased 1 amp diode to make it work. We use a web analysis program named ‘Google Analytics’, which allows us to optimise the website for your convenience based on anonymous website use data, without consulting any personally identifiable data.

I don’t know enough about electronics to know the reasons, but parallelling the LDDs apparently maxes out at about 1. To view links or images in signatures your post count must be 10 or greater. Safety depends if the LDD is also measuring switch or inductor current and not just LED cathode current it’s possible.


The time now is I wired both grounds common, i. It’ll still potentially mess with the compensation loop of each driver and you might end up with some hunting or flicker – it could be too high speed to see.

Just to clarify, you’re talking about recovery time from conductance to non-conductance in a standard p-n junction diode potentially causing an issue using PWM?
