IN +: Positive Input
IN -: Negative Input
OUT +: Positive Output
OUT -: negative Output

Note:

  • When you test if the output voltage is not higher than the input voltage, Please adjust potentiometer clockwise, Output voltage will rise.
  • Remember, please do not adjust the counter-clockwise, and trying to do step-down module,
  • Must ensure that the output voltage higher than the input voltage, so as not to damage the module!
Feature:
  • Input voltage: 3.5V-30V (must be set to ensure that the output voltage higher than input voltage)
  • Output voltage: 4.0V-30V
  • Input maximum current: 3A (According to the power conservation to Calculate Rated conditions Output Current
  • Uin * Iin * efficiency = Uout * Iout)
  • Continuous input current: 2A (good ventilation and cooling conditions the output voltage and input voltage ratio is not greater than 3)

Efficiency test is as follows:

DC-DC LED Driver With Constant Current Power Supply Step-down Module Test

5V to 12V

5V to 12V = (11.93 x 0.500) / (5.02 x 1.383) x 100% = 86.3%

DC-DC LED Driver With Constant Current Power Supply Step-down Module Test

12V to 24V

12V to 24V=(23.84*0.799)/(12.03*1.747)*100%=90.7%

Package Includes:

  • 1x DC Converter
