Build Adjustable DC-DC Converter on Flowerpad Protoboard

Step 8: Power and debugging

Double-check the circuit again before power on it. Make sure there is no any short current between IC pins. Check whether connection between components is reliable. 、

Finally， confirm the input and output poles is no short circuit. Power on the converter  then rotate the potentiometer，you can adjust the output voltage, and the voltage display on voltmeter.

I use this DCDC converter to power a 5W HB LED over 30 hours. As the tested result, it works stable and reliable.

Thant’s All. Thanks and Enjoy !!
