Oumefar Constant Current LED Driver, DC 3.3V 3.7V 5V LED Driver 30-1500mA Constant Current Control Module Constant Current Adjustable Module for LED Li Ion
【Current Regulation】This constant current led driver is a current regulation IC operating from the input voltage from 2.8V to 6V, the constant output current can be set up to 1.5A with an external resistor.
【Components】Constant current led driver consists of a high precision reference voltage, amplifier, current mirror, etc. The on-chip power transistor and the current sensor block greatly reduce the number of external components, making this product ideal for an LED driver.
【LED Driver】When the CE pin is high, the input voltage is greater than 2.8V and is greater than the LED forward voltage plus the required voltage drop, constant current led driver works normally to supply constant current from the LED pin.
【Temperature Control】Adopts temperature control instead of temperature function, temperature control can make the LED light continuously in case of high ambient temperature or high voltage drop. When the junction temperature reaches around 1
【Function】With e chip enable function, constant current led driver can turn off the whole chip to limit the current consumption within 1uA.
