Product Name: Ultra-small DC-DC module adjustable voltage module

   1, the input voltage 3-30V, output can be adjusted between 1.21V-18V (adjustable range for increasing the need for greater adjustable resistor), currently in an equal volume of DC-DC circuit, few can achieve such a high voltage.
      2, the maximum output current of 3A, 2A current recommended to use the following, leaving a certain margin. Without fins and airy case, power up to 20W or so, up to 93% efficiency.
      3, as is the step-down DC-DC circuit, the input voltage needs to be higher than output voltage 1.5V or more, in order to ensure the stability of the output voltage.
      4, with short circuit overheating protection, output short circuit is not afraid even if the circuit will automatically protect! Empty load, the static power consumption is only about 6mA.
      5, ultra-small size: 37x37x14mm.
