The MT7651L is a linear dimmable constant current LED driver IC, which can be widely used as the driver of dimmable light sources or lamps.
MT7651L is implemented with no EMI issues. Besides, no external magnetic component is required, small and low cost LED driving circuit is achieved.
MT7651L supports PWM dimming, the PWM signal is converted to internal reference voltage to realize smooth and no flicker dimming.
Embedded with line voltage compensation, the output current will be reduced when the input voltage exceeds the threshold, so as to ensure the input power does not change with the line voltage at the input range of 108Vac~132Vac.
MT7651L integrates thermal regulation function to balance the output power and system temperature. The output current will be reduced while the junction temperature goes higher than the threshold, system reliability is guaranteed.
