Frienda4 Pieces Adjustable LM2596S DC-DC Buck Converter Reduced Voltage Regulator Power Module 36V 24V 12V to 5V 2A Voltage Stabilizer with Digital Voltmeter Display
Main highlights- Simple to operate: the voltmeter can be turned off, and the switch can be turned off by pressing and holding the switch for more than 1 second and less than 4 seconds, once the voltmeter is turned off, simply press the switch to turn on the voltmeter
- Product parameters: input voltage is 4.0V - 40V, output voltage is 1.25V - 37V, output current is 2A (normal and stable) and 3A max, conversion efficiency 92% (highest), output ripple under 30mV, switching frequency 150KHz, operating temperature is -45 to 85 degree Celsius
- Output current: the maximum output current can be as high as 3A, the recommended working current is about 2A, more than 2A plus heat sink
- Nice design: with 150KHz internal oscillation frequency, features low power consumption and high efficiency; When the output voltage cannot be adjusted and is always equal to the input voltage, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally; This is because when the module leaves the factory, the default output voltage is about 20V
- Easy to use: with terminal block, no soldering iron is also convenient to use, and retain the wire bond point (the input voltage must be higher than the voltage to be output by 1v or more)

DROKDROK 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
Main highlights- 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.
- 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.
- 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.
- NOTE --- This mini buck converter is really very tiny, much smaller than a 1-dollar coin, nearly a half of the coin.
- High Efficiency --- Conversion efficiency: Up to 97% (typical value: >90% when step down 12V to 5V 2A).
