Mini LED dimmer and charger for lamps

Product detailed description

LED driver with PWM control technology designed for single-colour LED light sources, used for switching on, off, intensity control powered by LiION/LiPOL battery in 1S - 4,2V configuration. On/off and brightness control is done with one sensor button. The module also includes a LiION/LiPOL charger with the possibility of configuring the charging current in the range of 100-500mA by changing the resistor R3 on the PCB. The module can also be operated during charging, but it is necessary to remember that if the current drawn by the LED is greater than the charging current, the battery will not be recharged, but the difference current will be drawn from it and so the battery will be discharged even when the voltage is connected to the USB.

Module functions:

After connecting the battery, the module is immediately ready for use. From the factory it is set up so that it lights up and dims gradually using a sensor. When the button is pressed for the first time, the LED with the lowest intensity is triggered. The function has no settings memory.

The module enables mode switching - the first press of the sensor button triggers the LED light with the lowest intensity. Pressing again increases the intensity of the light up to the maximum. The module allows 3 levels of luminosity.

off -> low brightness -> medium brightness -> high brightness -> off

The mode change is made by connecting pin 8 of the integrated circuit and the soldering pad to the right of the pin:

Formula for calculating the charging resistor: R3 = _1000/Inab
