BP5711FK is a single-channel dimmable LED linear constant current driver chip, mainly used to drive various intelligent dimmable light sources and lamps with mains input. Based on linear constant current technology, BP5711FK can eliminate magnetic elements, helping LED drivers achieve small size, long life, and comply with EMI standards. BP5711FK supports PWM input dimming signals, and the output current is analog continuous, improving stroboscopic and EMI performance during dimming. BP5711FK has an over-temperature regulation function. When the input voltage is too high or the LED current is too large and causes the chip temperature to be too high, the output current will be reduced.
