Feature

●Parameter --- For DROK 12V to 5V voltage regulator: Input voltage: DC 4.5-20V; Output voltage can be adjustable or fixed. Adjustable range: 1-16V; Fixed voltage: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V; Output current: Max 3A (peak: 3A, long-term: within 2A); Power: 10W.
●Output Voltage Adjustable or Fixable --- These tiny 12v to 5v step down converters can be variable at output voltage. The small board is default to be used for output voltage adjustment. If you want to get fixed voltage output, you need to cut off the Pad A by using a sharp thing such as a knife then weld together the port of the fixed voltage you want.
●High Efficiency --- Conversion efficiency: Up to 97% (typical value: >90% when step down 12V to 5V 2A).
●Protection and Enable Control --- Output short circuit protection, but please do not keep short circuit for a long time. The integrated enable port defaults the working mode and it will be off when it is at low electric level off, which bring a great convenience for users.
●NOTE --- This mini buck converter is very tiny, much smaller than a 1-dollar coin, nearly a half of the coin.

Wiring

Correctly wire the module according to the instructions.

NOTE:

Input voltage: DC 4.5-20V

Adjustable output range: 1-16V

Trimmer Potentiometer

Use the trimmer potentiometer to adjust the output voltage.

NOTE:

Please be gentle, the potentiometer is quite weak. You may use a sharp plastic piece to get it work if theres no suitable tool.

Tiny buck converter

Please kindly note that this buck converter is really very small, much smaller than a 1-dollar coin, nearly a half of the coin.

Cut off this welding pad

First, cut off the welding pad below the trimmer potentiometer. This one is welded together by factory setting.

Please be gentle, you can use a sharp thing to scrape to disconnect it, just like the image.

Then choose a fixed output voltage you need

Then choose the fixed output voltage you need and weld it together, just like the image.

Last, finish the wiring
