LED driver claims world on a string

Raleigh, NC – Austriamicrosystems bills its AS3691 chip as the world’s first high-current with high-precision LED driver. “The IC’s absolute current accuracy of 0.5 percent allows for highly accurate brightness settings and is thus ideal for supporting sophisticated color management applications like LCD monitors with RGB backlighting,” said Ronald Tingl, marketing manager for Power Management. The AS3691 includes four independent high precision current sources each capable of sinking 400 mA (for four strings of RGB or single-color LEDs, or a single LED string for up to 1.6 amps).
