Hello - I’m attempting to power a RPi 4B from a 20V drill battery.
I purchased D36V28F5 from Pololu and it certainly works - but after ~30 minutes of power connected & the RPi in an idle state running no code I’m reading temperatures in excess of 130 F.
I’m new to spec’ing step-down DC voltage regulators and would love Pololus technical direction here.
- Should I purchase a buck with different characteristics (higher amperage rating?) or am I overlooking something else here?
- Is this temperature performance uncharacteristic for the product I purchased?
