When the CE pin is high, the input voltage is 2.8V, and is larger than the LED forward voltage plus the required voltage drop, LD06AJSA functions normally to deliver constant current from the LED pin. The LD06AJSA 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 the LD06AJSA ideal for LED driver. It 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 adopts the temperature regulation instead of temperature protection function, the temperature regulation can make the LED being turned on continuously in case of high ambient temperature or high voltage drop. When the LD06AJSA junction temperature reaches about 135 ° C, the internal temperature regulation block reduces the LED current so that the junction temperature not rise any more., Weight: 0.00220462262 pounds, Manufacturer: Hipzeepo
