DC-DC USB step-down charging module (with working indicator, standard contacts gold-plated socket)

 Product Size: 28*32*8mm

Product weight: 5.5g

Input voltage range: 6-26V

Output voltage: 5.2V (taking into account the loss of the charging line, the output is about 5.2V, the load is about 5V)

Output current: 3A (without heat sink, stable output current is 2A)

Note 1: The positive and negative poles cannot be reversed, and the input voltage cannot exceed 26V, otherwise it will damage the chip!

Note 2: When the power is on, you can't touch the sampling resistor and IC pin on the circuit board by hand, otherwise it may cause sudden change of output voltage and damage the device!

 For some customers with poor electronic foundation, please explain: Do not think that the nominal 3A current will burn mobile phone burning equipment! The charging current is determined by the mobile phone or device! The charging current of most mobile phones is 0.8-1.5A.
