A8600 Description
The A8600 is a high-efficiency driver for white light-emitting diodes (LED(s)). It is designed for large liquid-crystal displays (LCD(s)) that employ an array of LED(s) as the light source. A current-mode step-up controller drives up to six parallel strings of multiple series-connected LED(s).
A8600 Key Features
- Drives Six Parallel Strings with Multiple Series-connected LED(s) per String
- ±1.5% Current Regulation Accuracy Between Strings
- Low 450mV Feedback Voltage at Full Current Improves Efficiency
- Step-Up Controller Regulates the Output Just Above the Highest LED String Voltage
- Full-Scale LED Current Adjustable from 15mA to 25mA, or Preset 20mA
- Wide 100:1 Dimming Range
- Programmable Dimming Control: Direct
- Built-In PLL for Synchronized Dimming
- Output Over voltage Protection
- Wide Input Voltage Range from 4.5V to 26V
A8600 Applications
- Drives Six Parallel Strings with Multiple Series-connected LED(s) per String
