DC-DC step-down regulator module USB charging แปลงไฟจาก 6 - 26 Volt เป็น 5.2 Volt 3A

 

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)

 

Upper limit output current: 3A (in the case of no heat sink, the stable output upper limit current is 2A)

 

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!

 

Tip: This is a step-down charging module. The current indicated by 2A refers to the upper limit current of the load. It cannot be compared with the 2A current indicated by the charger.

 

For some customers with electronic basics: Do not think that the nominal 3A current will burn out the device! The charging current is determined by the device! The charging current of most devices is 0.8-1.5A.
