Amber Semiconductor’s AC direct DC power delivery technology is capable of converting DC directly from AC Mains without the use of transformers, rectifier bridges, or filtering. The AC Direct DC Enabler silicon chip enables dynamic delivery of DC power on demand, moreover, it requires a lower number of components for achieving power conversion, thus reducing the size, cost and complexity of designing a power converter. It can take a wide range of input from 25VAC – 277 VAC and provide a DC output from 1.8V to 24V. The AC direct DC power delivery technology will enable engineers to develop low-cost, compact power supplies or products running on low-voltage DC, it is ideally suited for integration into a broad range of electrical products such as smoke detectors, doorbell cameras, thermostats, smart products, appliances, intelligent HVACR, etc.

“Achieving tapeout is a key commercialization milestone for our breakthroughs that is not just important for AmberSemi, but also for our strategic partners and the industry as a whole, signalling a new era of solid-state electrification, a second electrical revolution of digital management of electricity,” said Thar Casey, CEO of Amber Semiconductor. “Our progress into the commercialization of our technologies is built upon a foundation of requirements defined and refined in conjunction with our strategic partners and over 30 successful technical evaluations with customers in the U.S. and Europe. These large companies have fully validated using AmberSemi’s technologies in discrete architecture, clearing the way to our manufacturing path in silicon.”

According to the company the AC direct DC power delivery technology will enable virtually any electronic device that uses DC power to run directly by plugging the AC mains. Furthermore, this technology can be paired with crucial semiconductor devices like microcontrollers and wireless radios for unique AC Direct semiconductor systems, that enable both housekeeping power plus outside sensor power provisioning from the single AC Direct system.

Amber Semiconductor is a Dublin, California-based company. The company develops innovative technologies for AC Direct digital management of electricity in silicon chip architecture.
