General Description
The GS7L08 is a LED backlight controller with six independent linear, programmable current regulators. The output current of each regulators can be respectively set by an external current-sense resistor.
The device supports pulse width modulation (PWM) brightness dimming by adjusting the DC level or duty of clock on the PWMIN pin. The recommended dimming frequency is from 100Hz to 2000Hz.
