Feature:

1. Temperature Regulation: The module uses a temperature regulation function that allows the LED to be continuously lit in case of high ambient temperature or high voltage drop.
2. Constant Current Module: This module is a regulation IC with an input voltage of DC 2.8 to 6V and can be set for constant output current.
3. Overcurrent Protection: When the LED current approaches 1.9A, the overcurrent protection block starts to work to prevent the LED current from increasing further.
4. 2 Adjustment Methods: Users can adjust the current of the constant current module by adjustable resistor or PWM control.
5. Ideal Choice: The module's power transistor and current detection block can greatly reduce external component counts and is ideal for LED drivers.
