A706应用电路(高压升压驱动器,带有6通道恒电流调节器)

The A706 is a high voltage Boost driver with 6 channels
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 VF variations. It
can drive a number of LEDs in series/parallel configuration
Users may adjust the output current from 5mA to 40mA
through an external resistor, RSET, which gives users
flexibility in controlling the light intensity of LEDs. It also
could adjust LED brightness from 0% to 100% via enable pin
(EN) with Pulse Width Modulation signal.
