Feature:1. Integrated Design: The constant current adjustable module includes a high ion reference voltage, amplifier, and sensing block, reducing the need for external components. making it suitable for LED drivers.2. Main Function: Led driver module features an enable function with an E chip, allowing for switching off the entire chip. The module consumes less than 1uA of power.3. Temperature Regulation: Instead of relying on a temperature ion function, the module uses temperature regulation to keep the LED continuously lit even in high ambient temperatures.4. Input Voltage Range: The constant current adjustable module operates within a voltage range of 2.8V to 6V, allowing for flexibility in various power supply setups.5. Adjustable Output Current: With the use of external resistors, the adjustable current LED driver module can be adjusted to set the output current at 1.5A.Specification:Item Type: LED Driver BoardMaterial: PCBOperating Voltage: DC 2.8 to 6VOutput Current:30 to 1500MALarge Output Power:9WFitment:For 3V 3.3V 3.7V 4.5V 5V 6V LED driver.Package List:1 x LED Driver Board Note:This product has 5 driver boards synthesized
