Product Description
MT7605 is a segmented linear constant – current LED driver. It operates in linear mode, according to the segment LED voltage drop automatically turns on different LED string without external settings to simplify the system design. No electrolytic capacitor, Inductor, transformer and other components are needed, low BOM cost is achieved.
MT7605 can drive three segment LED strings. When the input voltage varies, it lights up different segment LED strings automatically. In the one AC cycle, the LED light up time increases. This way, both efficiency and power factor improved. The PFC is as high as 0.99, THD can be less than 15%.
With Maxic’s proprietary current regulation method, MT7605 achieves ±3% accuracy of LED current. In addition, each segment of LED current can be set differently by individual sense resistors.
