The growing sophistication of modern electronic systems is driving increasingly tighter power supply specifications and requiring more intelligent power control methods. The switch to digital power control will happen gradually, but it will happen. Our job as silicon suppliers is to enable the transition by offering enhanced tools that meld the analog and digital worlds together to design more capable, higher performance power supplies. Properly engineered digital power can deliver a lower total cost of ownership, higher system reliability with predictive fault correction, and the ability for remote diagnosis and configuration—all tangible benefits for the customer.
Silicon Laboratories’ digital power solutions leverage our superior mixed-signal expertise to deliver solutions that enhance power system performance, flexibility and reliability, while reducing system size and cost. With proprietary digital control, isolation and high-voltage technologies, Silicon Laboratories’ innovative digital power product portfolio delivers exactly what the next generation of power hardware architectures need.
By definition, a digital power controller performs all system control algorithms in the digital domain. It converts all analog system parameters to digital, and uses this data to compute control response entirely in the digital domain, then writes the updated control information back into the system. Any controller doing less than this is “digitally assisted.” The precise, algorithmic nature of digital control enables more advanced control algorithms for increased system performance, its high integration delivers small size and low-cost control solutions, and its programmability enables hardware platform standardization with software customization for greater manufacturing efficiencies and faster time to market.
While the power supply designer is working to create more accurate, faster responding, more efficient and smaller supplies with each end-product generation, cost is also a key element. That said, system cost is more than just the bill of materials. Other tangible costs, such as manufacturing labor and overhead, customer support and warranty returns, must be included in any analog “break-even” analysis. To this end, digital power control has a long-term cost advantage over its analog control counterparts due to higher integration, and the cost savings resulting from the use of commodity digital IC fabrication technology.
Necip Sayiner serves as president and CEO of Silicon Laboratories and is a member of the board of directors. Necip joined Silicon Laboratories in September 2005, bringing to the company a strong mix of deep technical expertise in mixed-signal technologies and a proven capability to manage and grow large, diversified businesses.
Prior to joining Silicon Laboratories, Necip had a very fast rise within management at Agere Systems, where the 40 year old was vice president and general manager of the approximately $450 million Enterprise and Networking division. Necip established a track record of successful product execution, improvements in operational performance and growth initiatives with aggressive new product introductions. Necip’s ability to transform mature, legacy-oriented businesses to growth-oriented, highly profitable enterprises was a key factor in his success as the vice president and general manager of Agere’s Networking IC division. Necip also held several senior design management positions, and he holds multiple patents related to data detection schemes.Necip holds a bachelor’s degree in electrical engineering and physics from Bosphorus University in Turkey. He holds a master’s degree in electrical engineering from Southern Illinois University and a doctorate in electrical engineering from the University of Pennsylvania. Necip is married with three children and spends much of his personal time with his family. He enjoys traveling, basketball and tennis.
