ANALOG DEVICES ADP8863ACPZ-R7 发光二极管驱动器, 1输出, 电荷泵, 2.5V-5.5V输入, 1MHz开关, 30mA输出, LFCSP-20
Product Details
The ADP8863 combines a powerful charge pump driver with advanced autonomous LED lighting features. It allows as many as seven LEDs to be independently driven up to 30 mA maximum. The seventh LED can be also driven to 60 mA maximum. All LEDs are programmable for maximum current and fade in/out times via the I2C interface.
Additionally, automated blinking routines can be independently programmed and enabled for all seventh LED channels. These LEDs can also be combined into groups to reduce the processor instructions. Driving this entire configuration 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. The device includes a variety of safety features including shortcircuit, overvoltage, and overtemperature protection. These features 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.
The ADP8863 is available in a compact LFCSP lead frame chip scale package.
