Power Supply for WAV Trigger

Sensors Sound & Audio

What kind of DC-DC power supply would you recommend for the WAV Trigger? I am planning on using it in an automotive application where the supply voltage is ~13.8V. I was thinking a 9V buck converter, but am not sure.

Thanks

Hi gcm0285,

A 9V Step-Down/Buck Converter should work just fine for the WAV Trigger. Just make sure the converter you choose can handle the variations in voltage that can happen in an automotive circuit. The WAV Trigger will work powered either through the barrel jack connector or the two vias for VIN and GND next to that with any DC voltage between 6-15V.
