HW-681 6-26VDC to 5VDC 3A DC-DC Buck module

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

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

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

Input voltage range: 6-26V

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

Output current (dual socket): The total output current is 2A under normal heat dissipation conditions, and the total output current is 3A under the condition of fan cooling.

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

Note 2: When powering on, you can’t touch the sampling resistor and IC pin on the circuit board by hand. Otherwise, the output voltage may be suddenly damaged and damage the device!

Note 3: Do not think that the nominal 3A current will burn the mobile phone! The charging current is determined by the mobile phone or device! The charging current of most mobile phones is 0.8-1.5A.
