com   A8600 WHITE LED BACKLIGHT DRIVER SIX-STRING WITH ACTIVE CURRENT   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).
Each string is terminated with ballast that achieves ±1.
5% current regulation accuracy, ensuring even bright-ness for all LED(s).
The A8600 has a wide input-voltage range from 4.
5V to 26V, and provides a fixed 20mA or adjustable 15mA to 25mA full-scale LED current.
The A8600 has two d...
