Hello,
I recently bought a 20W Adjustable DC-DC Buck Converter with Digital Display. However, when i use the potentiometer to change the output voltage nothing happens, i have also tried to read the voltage using a multimeter.
Thanks
as this is a 20 watt capable device and i have a 5 volt apparatus that requires 4 amps
calculating this is a 20 watt load but the voltage regulator chip …
you guy`s state that it is a 3 amp device…
so would it meet my requirements…??
I have a similar problem to William. Despite calibrating the board with the DFRobot process, nil change in the output voltage regardless of what I do with the adjustment screw. What’s the secret I am missing?
Thanks.
