TC4056A 3,7V 4,2V 9V 5V 2A 18650 lítium akkumulátor töltés, kisütés, integrált állítható modul multiméter módosítás
TC4056A 3.7V 4.2V 9V 5V 2A 18650 lithium battery charging boost discharge integrated adjustable module multimeter modification
Debug well before use, the default output is about 9V
Input voltage 4.5~8V
The output voltage is continuously adjustable 4.3~27V
(Above 4.3V and below 27V, any voltage can be output, you can adjust it yourself, adjust the boost counterclockwise)
Charging voltage 4.2V, charging current maximum 1A
The maximum discharge current is 2A, and the output current must be calculated by yourself
Output reference maximum current 5V 1.4A, 9V 0.8A, 12V 0.6A
Quiescent current is about 0.5 mA
Overcharge protection: Yes
Over-discharge protection: None (it can also be said that there is 2V cut-off boost, but the output is not blocked, the output is still 2V)
Cut-off boost 2V depending on the situation, whether to add a protection board
Size: 33*23*9mm
For example, the VIN terminal is connected to a 5V solar panel, and the BAT terminal can output 4.2V to charge a 3.7V 18650 battery.
The OUT terminal can output an adjustable voltage, you can adjust as much as you need
Can be used to charge multimeters and modified lithium batteries
