DROK DC 12V to 5V Buck Converter, 10pcs Mini Voltage Regulator Board DC 4.5-20V 12V 9V Step Down to 1-16V 5V Reducer 3A Fixed Adjustable Volt Output Transformer Power Supply Stabilizer Module

Parameter --- For DROK 5V volt step down 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 --- The tiny buck converter board can be changed to adjustable output voltage or a fixed one. The reducer is default to be used for adjustable voltage output. 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 --- Big energy in small size. The conversion efficiency of this volt transformer can be up to 97% (typical value: >90% when step down 12V to 5V 2A).
Protection and Enable Control --- The 12V buck converter is designed with output short circuit protection, but please do not keep short circuit for a long time. Also, the reducer is equipped with an integrated enable port which defaults the working mode that 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 really very tiny, much smaller than a 1-dollar coin, nearly a half of the coin.
