BP5778EK is a dual-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, BP5778EK can eliminate magnetic elements, helping LED drivers achieve small size, long service life, and comply with EMI standards. BP5778EK supports PWM input dimming signals, and the output current is analog continuous, improving stroboscopic and EMI performance during dimming.
