DC 2.8-6V Constant Current Regulator Module,9W 30-1500mA Adjustable Module,LED Driver Transformer,for LED Driver 18650 Li-ion

PROFESSIONELL GEMACHT:This LED Driver Transformer is a current regulation integrated circuit operating from an input voltage of 2.8V to 6V, the constant output current can be set up to 1.5A with an external resistor. FEATURE:Constant Current Regulator Module, It consists of high precision reference voltage, amplifier, current mirror, etc. The on-chip power transistor and current sense block greatly reduce the external component count, which makes this product ideal for LED driver. DELIVER CONSTANT CURRENT FROM THE LED PIN:When the CE pin is high, the input voltage is greater than 2.8V, and is larger than the LED forward voltage plus the required voltage drop, it functions normally to deliver constant current from the LED pin. WITH E CHIP ENABLE FUNCTION:Adjustable Current LED Driver ,With e chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA. OVER CURRENT BLOCK:Adjustable Module,Adopts the over current block. When LED current approaches 1.9A(Typical), the over current block begins to function to prevent the LED current from increasing further.
