Overview
- Charge pump with automatic gain selection of 1x, 1.5x, and 2x for maximum efficiency.
- 92% peak efficiency
- 9 independent and programmable LED drivers
- Each driver capable of 25 mA (full scale)
- PWM input for implementing content adjustable brightness control (CABC)
- Dedicated reset pin and built-in power on reset (POR)
- See datasheet for additional features
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 out times can be set for the backlight LEDs.
Driving all of this is a two capacitor charge pump with gains of 1×, 1.5×, and 2×. This setup is capable of driving a maximum IOUT of 240 mA from a supply of 2.5 V to 5.5 V. A full suite of safety features including short-circuit, overvoltage, and over-temperature protection allow easy implementation of a safe and robust design. Additionally, input inrush currents are limited via an integrated soft start combined with controlled input to output isolation.
APPLICATIONS
- Mobile display backlighting
- Mobile phone keypad backlighting
- LED indication and status lights
- Automated LED blinking
