132 LED driver features industry’s highest efficiency and smallest size
Austriamicrosystems has announced the AS1130, which it claims is the most advanced and smallest dotmatrix LED driver (channels vs. PCB space) available. The AS1130 drives 132 LEDs but requires only 5 mm² PCB space, reduces external component count, allows use of cheap connectors and requires fewer PCB (printed circuit board) layers. Benefits for end users include up to 80% longer battery lifetime, more colourful effects and smoother running animations.
Using a 12×11 cross-plexed technique, the AS1130 LED driver is targeted for dot-matrix displays in mobile phones, toys, small LED displays in personal electronics, but also non-battery powered household goods, indoor public information displays, and industrial applications such as power meters.
