LED Driver Module Adjustable Constant Current Voltage 3.3V 3.7V 5V 30-1500mA for USB Li-ion Boards

Application: 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. For LED driver: It consists of high precision reference voltage, amplifier, current mirror, etc. The on-chip power transistor and current sense block reduce the external component count, which makes this product for LED driver. Deliver constant current: 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. function: 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 Enable function: With e chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA
