DC-DC Boost Power Supply Module LM2577 Step-Up Converter DC 3.5-35V to 5-56V 3A Step Up Power Supply Board with Indicator Light
Note:
When you test the output voltage if the output voltage is not higher than the input voltage, adjust the potentiometer clockwise, the output voltage will rise. Remember that the output voltage is set higher than the input voltage, so as not to damage the module!
IN+ input positive
IN- input negative
OUT+ output positive
OUT- output negative
Specifications:
Input voltage range: 3.5V-35V (must ensure that set the output voltage is higher than the input voltage)
Output voltage range: 5.0V-56V
Enter the maximum current: 3A (according to the power conservation to calculate the rated current output current
Uin*Iin*Efficiency=Uout*Iout)
Input continuous operating current: 2A (ventilation cooling conditions good output voltage and input voltage ratio can not be greater than 3 times)
Dimensions: length*width*height 4.3cm*3.0cm*1.2cm
The work efficiency test is as follows:
5V to 12V:
5V to 12V= (11.93*0.500) / (5.02*1.383) *100%=86.3%
12V to 24V:
12V turn 24V= (23.84*0.799) / (12.03*1.747) *100%=90.7%
