MT7609 is a high efficiency, high PF (PF>0.7), linear LED driver with wide input voltage range. The output constant current can be achieved by simple system structure with a few peripheral components, which greatly reduce the system cost.

MT7609 integrates twin constant current control loops, which makes it can support 108Vac to 265Vac wide input voltage range.

Embedded with rectifier bridge, freewheeling diode, high voltage power MOSFET and JFET supply circuit, the peripheral circuit is further simplified.

MT7609 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.
