Mini Solar Charger CN3163 CN5711 Solar LED Drive Module Solar Panel Regulator Controller Voltage 4.4V-6V 4.2V Solar Panel Lithium Battery Charging Module - KUFptva, KUH13AC1500871

• The LED driver board integrates the solar charging chip CN3163 and the high-brightness LED driver chip CN5711, which can be used for DIY production of solar-charged LED lights, solar street lights, lighting fixtures, etc. Just plug in a 5V solar charging board, a rechargeable lithium battery and a 37V LED light to easily form a solar charging LED light. CN5711 is a current modulation integrated circuit with a constant output current of up to 1.5A. It can be used to drive various types of light-emitting diodes including white light-emitting diodes. The LED terminal current of CN5711 is set by an external resistor, and the current range is 30mA1.5A . The power transistor is integrated inside the chip, which greatly reduces the number of external components. CN3163 is a single-cell lithium battery charging management chip that can be powered by solar panel. The internal charging current adaptive module can automatically adjust the charging current according to the current output capacity of the input power supply. The user does not need to consider the worst for case, and can maximize the current output capacity of the input power supply.
