Descriere 1PCS 3.3V 3.7V 5V LED Driver 30-1500MA Constant Current Adjustable Module PWM Control Board for USB LED Flashlight

It is a current regulation integrated circuit operating from an input voltage of 2.8V to 6V, the constant output current can be set to 1.5A with an external resistor.
The LD06AJSA consists of high precision reference voltage, amplifier, current mirror, etc. The -chip power transistor and current sense block greatly reduce the external component count, which makes the LD06AJSA ideal for LED driver.
When the CE pin is high, the input voltage is greater than 2.8V, and is larger than the LED forward voltage the required voltage drop, LD06AJSA functions normally to deliver constant current from the LED pin.
It adopts the temperature regulation instead of temperature protection function, the temperature regulation can make the LED being turned 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 will not rise any more.

This feature allows the users to maximize the use of the power handling capability of the chip, do not worry about the chip overheating and damage to the chip or external components.
It also has the chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA.
It also adopts the over current protection block. When LED current approaches 1.9A(Typical), the over current protection block begins to function to prevent the LED current from increasing further.
