LED controller puts on a light show

Kirchheim/Teck, Germany – Dialog Semiconductor’s new DA9026 controller is designed to program up to 18 light-emitting diodes (LEDs) for running the “fun lights,” light shows, and backlighting in cellular handsets, handheld games, and other portable devices. It incorporates on-chip memory to store up to 15 light-pattern sequences and can drive separate red, green and blue LEDs (i.e., six RGB LEDs) using precision current d/a converters (DACs). Programmable variables include pattern, repetition rate, intensity of each LED, and sequence duration.
