Constant Current Module, Practical Multifunctional Stable Adjustable Module, for LED Pin Industry for Current Control of LED Drivers
This product 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.
It consists of high 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.
Adopts the temperature regulation instead of temperature function, the temperature regulation can make the LED being turned on continuously in case of high ambient temperature or high voltage drop. When the junction temperature reaches about 1
With e chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA.
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.
