A8600 Datasheet PDF (WHITE LED BACKLIGHT DRIVER SIX-STRING)

A8600 - WHITE LED BACKLIGHT DRIVER SIX-STRING

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).

Features

to protect the controller from fault conditions. Separate feedback loops limit the output voltage if one or more LED(s) fail open or short. The controller features cycle-by cycle current limit to provide consistent operation and soft-start capability. A thermal shutdown circuit provides another level of protection. The step-up controller uses an external MOSFET, which provides good efficiency and allows for scalable output power and maximum operating voltage. Low feedback voltage at each LED str.

AiT Semiconductor Inc. www.ait-ic.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 dimming control modes to enable a wide variety of applications.
