The FAN5702 is a highly integrated and configurable charge chargepump- based multi-LED driver. The device can drive up to six LEDs in parallel with a total output current of 180 mA. Regulated internal current sinks deliver excellent current and brightness matching to all LEDs.
The FAN5702 has an I2C 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 I2C 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 ISET values of 30 mA, 20 mA, 15 mA, or 8 mA. The default ISET is always determined by the ISET ordered.
