CURRENT REGULATION INTEGRATED CIRCUIT: This adjustable LED driver 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
IDEAL FOR LED DRIVER: 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
E CHIP: Adjustable Converter with e chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA. When LED current approaches 1.9A(Typical), the over current block begins to function to prevent the LED current from increasing further
TEMPERATURE REGULATION: 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
ABOUT INPUT VOLTAGE: 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
