Control electronics for 50V applications

Offentlig prosjektsammendrag

poLight develops and produces active lens elements, primarily for small cameras in applications like mobile phones. New products such as optical image stabilizers (OIS) and shutter/Iris are also envisaged. To enable extended application range, as well as new applications for our products, we have started an activity for designing and manufacturing a novel ASIC driver with increased voltage capability (50V). Higher available voltage will enable more optical power. The main challenges to be addressed in this project are related to the trade-offs between performance, size and cost. High voltage capabilities while keeping low power consumption, good ESD (Electro Static Discharge) tolerance and low EMI (Electro Magnetic Interference) normally come at a cost of increased device area, thus price. A smart design, using novel solutions, is required to obtain a device that meets the market tough requirements in terms of both performance and cost.
