A buck converterHi, what would be the best way to step down 12V dc and 24Vdc to 5Vdc for a microcontroller please?
if for signal inputs use voltage dividers or optocouplers.Hi, what would be the best way to step down 12V dc and 24Vdc to 5Vdc for a microcontroller please?
Hi Papabravo, I would like to to use a microcontroller to blink a couple of 12V lights on my car and then a truck I have. Car is 12Vdc and truck is 24V dc. Hope that clears it up?? Hence using a microcontroller will be the easiest for me but will need to be powered.Ambiguity reigns supreme! You should try to be more precise about your requirements.
Are you powering JUST the microcontroller, or other items such as relays?Hi Papabravo, I would like to to use a microcontroller to blink a couple of 12V lights on my car and then a truck I have.

Use a Recom R-785.0-0.5 (6.5V to 32V input and good for voltage spikes in vehicles). Check output current (max 0.5A) and switching noise (may need a small LC if anything sensitive).Hi, what would be the best way to step down 12V dc and 24Vdc to 5Vdc for a microcontroller please?
