Dimmable Direct-AC LED Driver (8 Pins)



The LS9100x is a High Voltage full-bridge rectifier combined with a current limiter source circuit and protection circuit. Its rugged design is optimized for driving LED banks directly from the main utility line eliminating external components by merging them into a…

Dimmable LED Driver (8 Pins)



LS9200 is a monolithic CMOS device for driving and dimming LED networks. The regulated constant current is maintained with an external sense resistor forming part of a feedback loop. The maximum LED load current is set by the sense resistor whose duty cycle can be modulated with a built in PWM circuit. The Pulse Width modulated duty cycle results in chromatic shift-free dimming over the entire range of 0% to 100%
