Part Number:LM3409HV
I am using the LM3409HV as a modular panel driver. meaning you can add different LEDs to the output, with different specs (stack voltage from 11-22v and what not).
Firstly let me know if allowing different stack voltages with this chip will end up being a pain, because it is now. and im wondering if i should switch to another chip.
But the big questions is when i am using FET dimming, when the N-ch gate is going low, the Output voltage is ringing and spiking a lot.
Any help would be super, Do you guys have any suggestions on what are some common fixes,
