Applications

1). DIY an adjustable power supply, only need to enter a transformer or a connected laptop power adapter on it, the output voltage you can freely adjust, but the output voltage can not exceed the input voltage Oh.

2) The real universal charger, you have this power you can charge the battery of any type, for example, you want to charge the battery, just put the module output voltage is regulated to 4.2V on it. If you want to nickel-metal hydride battery, just need to adjust the output voltage to 1.4V on it, if you want to charge the battery, just need to adjust the voltage to the float voltage to your battery, fully charged, he will naturally not sufficient, and if you want to slow charge, only a series resistor in the output.

3) In order to power your electronic devices, as long as the voltage regulator to your desired voltage and current does not exceed the rated current can all be working.

4) When you do a project, when asked to enter the time for the 9-30V, and your system board is 5V power supply, with the 7805 heat and too much, then you choose this module we will be your best choice, you can not debug directly on the welding work, easy to do efficient wide voltage input.
