Introduction

AI Translation

The FAN5702 is a highly integrated and configurable 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.
