DROK DC 5V Power Converter, 5pcs Mini Voltage Buck Regulator DC 4.5-20V 12V 9V Step Down to 5V Reducer Transformer Board 3A 10W Adjustable Fixed Volt Output Step-Down Power Supply Stabilize
Parameter --- For DROK mini buck converter, 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.
High Efficiency --- Conversion efficiency: Up to 97% (typical value: >90% when step down 12V to 5V 2A).
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.
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 really very tiny, much smaller than a 1-dollar coin, nearly a half of the coin.
