Charge Pump Driven 9-Channel LED Driver

Data Sheet Charge Pump Driven 9-Channel LED Driver with Automated LED Lighting Effects ADP8866 FEATURES Charge pump with automatic gain selection of 1×, 1.5×, and 2× for maximum efficiency 92% peak efficiency 9 independent and programmable LED drivers Each driver is capable of 25 mA (full scale) Each driver has 7 bits (128 levels) of nonlinear current settings Standby mode for <1 µA current consumption 16 programmable fade-in and fade-out times (0.0 sec to 1.75 sec) with choice of square or cubic rates Automated and customizable LED blinking Unique heartbeat mode for programmable double pulse lighting effects on 4 channels (D6 to D9) PWM input for implementing content adjustable brightness control (cABC) I2C compatible interface for all programming Dedicated reset pin and built-in power on reset (POR) Short circuit, overvoltage, and overtemperature protection Internal soft start to limit inrush currents Input to output isolation during faults or shutdown Operates down to VIN = 2.5 V, with undervoltage lockout (UVLO) at 1.9 V Small lead frame chip scale package (LFCSP) GENERAL DESCRIPTION The ADP8866 combines a programmable backlight LED charge pump driver with automatic blinking functions. Nine LED drivers can be independently programmed at currents up to 25 mA. The current level, fade time, and blinking rate can be programmed once and executed autonomously on a loop. Separate fade-in and fade-out times can be set for the backlight LEDs. APPLICATIONS Mobile display backlig.
