1. Precision Adjustment Enjoy the immense versatility of the constant current LED driver module. This product with an operating input voltage range of 2.8V to 6V provides a constant output current of up to 1.5A. This module is characterized by LED lighting and Liion batteries, making it suitable for hobby electronics and DIY projects. 2. Ingenious Component Composition The constant current adjustment module features a selection of carefully crafted components, including a precision reference voltage, an amplifier, and a current mirror. The system integrates an onchip power transistor and a current detection block. These features make it ideal for use as an LED driver. 3. Reliable Performance This PWM control board ensures exceptional performance when the input voltage exceeds the required voltage drop and LED forward voltage. Under these conditions, it successfully delivers a constant current from the LED pin. 4. Temperature Regulation The DC constant current adjustment module employs temperature regulation instead of mere temperature protection. This crucial function enables continuous LED operation even under unfavorable conditions, such as elevated ambient temperature or voltage drop.
