adjustable constant current regulators for notebook LED

backlight applications. Six regulated current ports are designed to

provide uniform and pure DC constant current sinks for driving

LEDs within a large range V

LEDs in series/parallel configuration

through an external resistor, R

controlling the light intensity of LEDs. It also could adjust LED

brightness via PWM pin with Pulse Width Modulation signal

and the Current Regulators. It could sense the lowest dropout

voltage among used channels to Boost Driver in order to maintain

the output voltage in optimal level. An OVP circuit is built for

open-loop protection when any string becomes open.

The A706 is a high voltage Boost driver with 6 channels

Users may adjust the output current from 5mA to 40mA

A feedback circuit is built in the between of Boost Driver

The thermal protection function protects IC from over
