How do you work out the maximum current a buck converter can handle at different voltage outputs? The one I am looking at specifies :
- 300W 12A Adjustable CC CV Step Down Buck Converter 7-32V To 0.8-28V Power Supply
- Non-isolated step-down module, constant current and constant voltage module (CC CV), charging module
- Input voltage: 7-32V
- Output voltage: 0.8-28V (continuously adjustable)
- Output Current: 12A
For example, if I have a motor connected to the output and have the following configurations, what is the maximum current the converter can supply?
- 24v in, 12v out
- 24v in, 9v out
- 24v in, 6v out
I thought it would be the power over the output voltage, so in the first example, 300/12, but that is 25A, which seems far too high
I'm not sure how the specified 12A relates?
