The FAN5702 is a highly integrated and configurable charge-
pump-based multi-LED driver. The device can drive up to six
LEDs in parallel with a total output current of 180mA.
Regulated internal current sinks deliver excellent current and
brightness matching to all LEDs.
The FAN5702 has an I 2 C interface that allows the user to
independently control the brightness with a default grouping of
2,1,1,1,1 for a maximum of five independent lighting channels.
The LED driver can be programmed in a multitude of
configurations to address broad lighting requirements for
different platforms. Each LED can be configured through I 2 C
as five independent channels (Group A has two LEDs by
default) or any additional LEDs can join Group A to increase
the backlighting needs as the display size increases. The
device offers a second dimming control using the EN/PWM
pin. Applying a PWM dimming signal to this pin allows control
of the dimming of Group A LEDs so that the average current is
the linear value multiplied by the PWM dimming duty-cycle.
The device provides excellent efficiency, without an inductor,
by operating the charge pump in 1.5x or pass-through mode.
The FAN5702 can be ordered with default I SET values of

30mA, 20mA, 15mA, or 8mA. The default I SET is always
determined by the I SET ordered (see Ordering Information) .
