Using TSMC's 40 nm process, this collaboration aims to enhance performance and efficiency with minimal power consumption, setting new standards for touch controller product efficiency.

This partnership enhances SigmaSense's SDC300 series chips through the integration of Dolphin Design's DC/DC converters, which demonstrate efficiencies exceeding 85%. The DC-DC converter also maintains a low quiescent current of 300nA. Furthermore, to bolster system robustness against noise, the SDC300 series integrate a micro-LDO with fast transient response and high PSRR features. Touch controllers, known for their sensitivity to system noise, have benefited significantly from Dolphin Design's IP, which was instrumental in enhancing product robustness and achieving time-to-market milestones.

“We are thrilled to partner with SigmaSense, a leader in the field of interactive display technologies. This collaboration demonstrates our commitment to delivering robust and efficient power management solutions tailored for noise-sensitive systems across the industry”, said Philippe Berger, CEO at Dolphin Design.

David French, CEO at SigmaSense, adds “Dolphin Design’s highly dependable power regulators and deep expertise in ultra-low power management solutions integrated with SigmaSense technology will accelerate game-changing sensing products, and help transition to a universe of new data-centric design options driven by software-defined sensing.”
