100% Brand New and High Quality
This module is a constant current Stepup LED Driver, with a great degree of configuration.
The default constant current driver is 650mA, suitable for a 1W LED. The constant current value can be adjusted by changing the current sensing resistor.
【Current conversion formula: 0.22V / sampling resistance (the default is two 0.68Ω parallel) = 0.22 / 0.34 = 0.647A, Remove one 0.68R, current is 0.22v/0.68=0.32A, And so on.】
Main IC: XL6003
Input Voltage: 3.6V to 36V (best for 12v input)
Efficiency: 90%, Switching current max is 1.5A
High voltage Output : Max 50V
Dimension: 30*13.5*5mm
Example application:
1. Single Lithium ion battery 3.7V Drive two to three 1W LED connected in series, two to five 0.5W LED connected in series.
2. 5V input can drive eight 1W LED connected in series
3. The maximum voltage output is 42V, i.e. around 12pcs 1W LED connected in series, (of course the input voltage will need to be higher, around 24V will be OK)
NOTE: Connect the LED before connecting the power supply. If there is no LED connected but there is power supply, the circuit will stepup the voltage to maximum (around 50V), this may damage the LED if they are connected after connecting the power supply.
Package Included:
1 x Lithium Li-ion 18650 Battery Stepup CC LED Driver Module
