Description

• DC 2 Adjustable 28-1500mA LED Constant Current Driver Board for Flashlight Headlights Emergency Lights 3V three 3 5V 6V Product promoting points: 1. Use superb materials with assured high quality 2. Small length and beautiful appearance 3. LED overcurrent protection 4. Easy to use 5. Wide application differ Parameters: Working voltage: DC 2 (very correct for 3V 3 3 5V 6V LED drivers) Output current: 28-1500MA Maximum output power: 8W Output latest accuracy: ± 5% Capable of using 1-16 2 LEDs (maximum current no longer exceeding 1) Current regulation: 1. Through adjustable resistors; 2 controlled by way of way of PWM Chip temperature legislation LED overcurrent protection Working temperature range: -40 ℃~+85 ℃ Size: 20mm x 10mm x 2 Weight: approximately zero grams Description: This product is a modern regulating included circuit with an enter voltage of 2 to 6, and a constant output current of one can be set utilizing an outside resistor. The product involves high-precision reference voltage, amplifier, latest mirror, etc. The on-chip power transistor and the electrical influenza reaction block enormously reduce the number of external components, making this product a perfect desire for LED drivers. When the EN pin is at excessive voltage, the input voltage is bigger than 2 and is bigger than the LED ahead voltage plus the mandatory voltage drop, the product operates veritably and provides a constant recent from the LED pin. This product adopts temperature legislation rather than temperature defense function, which may continuously remove darkness from the LED when the ambient temperature is excessive or the voltage drops. When the junction temperature of the product reaches about a hundred thirty five ° C, the inner temperature regulating block will lower the LED current, making the junction temperature not rise. This operate permits users to maximise the power processing means of the chip without annoying about overheating and damage to the chip or external components. This product also has chip enable function, which might turn off the entire chip and restrict current intake to inside 1uA. This product also uses overcurrent defense blocks. When the LED recent approaches 0 (typical), the overcurrent protection block starts to function to forestall extra expand in LED current. Package List: Driver module * 1
