   The built-in maximum 1 A linear charging mode of charging current is adjustable

Технічні параметри:

Built-in maximum 1A linear charging mode, charging current can be external
Tune
◆ Trickle/constant current/constant voltage three-stage charging, 4.20V/4.35V available
Optional, support 0V battery charging;
◆ The built-in charging can automatically reduce the charging current according to the temperature rise, 130
The degree begins to decrease, and the lowest can be reduced to 0;
◆ The booster uses a synchronous rectifier circuit, with the highest efficiency exceeding
90%, low heat generation, fixed 5.1V output, no need for external
Resistance setting;
◆ Boost output current 1A (BTP=3.6V);
◆ With constant power output function, complete over-current, short-circuit
Protection, built-in temperature protection automatically stops the boost when over temperature;

Automatically start boost when load is inserted, and automatically stop when load is removed
sleep;
◆ The four-light indicator mode can indicate the battery power more accurately.
With battery low voltage reminder function;
◆ There is a port for setting Apple D+, D- voltage divider resistance setting
DPDN, with an NTC setting port, can control

Control system safe working temperature
◆ It can directly drive the LED flashlight with a drive current of 50mA
◆ Fixed switching frequency 1MHZ
◆ Battery overcharge and overdischarge protection
