Hi guys,
I Have a teensy LC connected to an RGB strip. The first time I tried connecting both of them to the same power supply (5V), the teensy LC fried the moment the RGB lit up. It was because there was a voltage droop, and the moment there was a load (RGB lit up), the voltage from the power supply fluctuated from 4.7 to 5.3 or even higher. Is there a simple circuit to stop that from happening ? When I power the teensy with my computer and my strip with the power supply everything is working perfectly. But it instantly fried when I played a sound on my first try when they were sharing the power supply. I already did a thread about it, asking what the problem was, but now I think this is the problem.
I already finished my PCB, do you know any simple circuit that I can add just before the Vin on the Teensy LC to try and reduce the voltage droop so I can use the same power supply with both RGB and Teensy LC.
Do you think adding a simple diode will drop the voltage enough so it never exceeds the maximum Vin voltage ?
Thank you !
