Programmable LED driver enables independent control of nine LED sinks
April 21, 2011 // Paul Buckley
Analog Devices, Inc., has released the ADP8866 LED charge pump backlight driver, which features independent control of nine LED current sinks, programmable LED blinking sequences and low operating current drain. Independent LED control allows designers to program different currents for each channel and enable them at different times.
The feature allows the convenient control of backlighting LEDs and status indicator LEDs with one part. Programmable fade on/off and blinking sequences allow complex LED effects to be generated automatically, saving processor bandwidth and power. A built-in charge pump automatically adjusts its gain to efficiently power the LEDs under all conditions.
Requiring less than 1 µA during standby and less than 325 µA during automated blinking sequences, the ADP8866 programmable LED driver’s low power consumption and simplified software interface make it an excellent choice for portable systems which require a high number of LEDs that need to be independently controlled. Such requirements are commonly found in keypad lighting, LCD lighting and analysis lighting applications. Evaluation boards are available, providing engineers with the necessary tools to implement their designs quickly and efficiently.
