• Bởi pe1osq 18/08/2015 I used this module to build a variable power supply. I use an input voltage of 12 volts (from a computer power supply) and need this module to create a variable (settable via the potmeter) output voltage ca 1 - 30 volt. With output voltages over 12 volts everything works fine. In the step down mode (voltages below 12 volt) the output voltage is not stable. For instance if I set the output voltage to 5 volts and apply no or very little load, then the outputvoltage "swings" between 4.8 and 5.3 volt.
