12V/24V to 5V Dual Socket 3A DC-DC Vehicle Charging Stable Voltage Charging Module HW-681

Dual socket 3A DC-DC step-down regulator charging module

Product size: 28*33*8mm (dual socket), 28*66*8mm (four socket)

Product weight: 5.5g (dual socket), 11.5g (four socket)

Input voltage range: 6-26V

Output voltage: 5.2V (considering charging line loss, the output end is about 5.2V, and the load end is about 5V)

Output current (dual socket): 2A total output current under normal cooling conditions, 3A total output current under fan cooling conditions.

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

Note 2: When the power is on, the sampling resistor and IC pin on the circuit board cannot be touched by hand, otherwise the output voltage may be abruptly damaged and damage the device!

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