LED Drivers

The LX27901 is an extremely versatile high-performance controller for driving LEDs from the HVDC (output) rail of a standard PFC front-end. The controller allows the user to utilize three different converter drive schemes, LLC (resonant), conventional PWM control, and Microsemi’s proprietary synchro ·LLC, PWM and proprietary synchronous modes to drive the LED strings\n·LED strings can be dimmed by PWM or analog methods\n·Proprietary algorithm to provide accurate brightness control at high efficiency over wide dimming duty cycle range\n·Accurate parallel LED strings current matching using Micros;
