XML T6/U2/L2 driver board 7135*8 five-speed dimming flashlight driver circuit board 17MMConstant current drive circuit boardThe parameters of the high-power LED driver board are as follows:1. It is suitable for a lithium battery to supply power, and it can be used between 3.0-4.5V input.2. Using 8 genuine 7135IC constant current IC output, the output current is sufficient 2.8A3Imported MCU IC dimming, five-level dimming: strong--medium--weak--burst flash--SOS(You can short-circuit the stars on the back to change to third gear or second gear dimming)4. IC built-in over-temperature protection, circuit design with reverse lithium battery protection. When the lithium battery is reversely installed, the circuit board, light bulb and lithium battery will not be damaged.5. Adopt double-sided immersion gold PCB board, good quality, drive circuit board diameter 17MM, double-sided electronic components, PCB board thickness 1.6MM, total circuit thickness 5MMThis driver board is suitable for a single lithium battery flashlight, etc. to drive a 10W high-power CREE XML T6, L2 LED.6. Drive circuit with low-voltage protection, under-voltage mode: using a dedicated voltage detection chip, when the voltage is lower than 2.9V, the lamp beads turn to low light and flash slowly as a reminder! The drive circuit without low voltage protection does not have this function.7. Weld the positive and negative red and black wires of the output end of the drive circuit, connect the red wire to the positive electrode of the lamp bead, and connect the black wire to the negative electrode of the lamp bead. Weld the input positive spring on the back, which is convenient for assembly and use!![]()
