Backlight LED Driver

The ET5119A/B/C is an asynchronous constant-current LED driver capable of efficiently driving a string of up to ten LEDs in series. The high fixed switching frequency allows the use of small chip inductors and capacitors. \r\n The ET5119A/B/C uses a simple single-wire digital control interface t • Drives up to 10 LEDs in Series(ET5119A)\r\n• 2.7V to 5.5V Input Voltage Range\r\n• Single-Wire Digital Control Interface to Set LED Brightness 32-Levels Linear Steps\r\n• Soft-Start Capability\r\n• Output Over-Voltage protection \r\n ET5119A：36V\r\n ET5119B：24V \r\n ET5119C：19V\r\n• Over-current, ;
