The SFBAC (combined Santa Clara Valley, San Francisco, & Oakland/East Bay) IEEE Power Electronics Society (PELS) is very excited and honored to have Keith Kunz, a Distinguished Member of the Technical Staff at Texas Instruments, to speak on the topic of Low Quiescent Current (Iq): Extending Battery Life Without Compromise

Minimizing Iq is a key factor in managing battery life and enabling energy harvesting solutions. An Internet-of-Things (IoT) sensor node is one of the best examples of why it's important to minimize Iq. Because these types of systems spend the majority of their time (>99%) in standby mode, the Iq in standby mode tends to be the limiting factor for battery life and utilizing energy harvesting techniques. Careful optimization of low-Iq power management blocks makes it possible to extend battery life from two years to more than ten years. Recent breakthroughs have been achieved in reducing Iq <60nA for power management building blocks such as DC/DC converters, power switches, low-dropout regulators (LDOs) and supervisors without the classical trade-offs . More importantly, this presentation will highlight some of the pitfalls to avoid and remaining challenges on the journey to achieving lower Iq.

Keith Kunz of Texas Instruments


Low Quiescent Current (Iq): Extending Battery Life Without Compromise


Keith Kunz grew up in Bryan, College Station, Texas, and received his bachelor’s degree cum laude in electrical engineering from Texas A&M University. He has been with Texas Instruments since 1992. Keith is passionate about predicting new markets of opportunity based off of future trends and figures of merit and analyzing how they will intersect with the advancements in circuit, process and package technologies. During the last 15 years, Keith has taken up roles as a designer, design manager, design lead and technologist around the world at TI’s Dallas, Nice, Bangalore and Tucson design centers. He has been granted more than 25 US patents that have influenced the introduction of new process components, Nano-power IP and isolated power circuits, and improved power density technologies. Keith became a Distinguished Member of the Technical Staff at TI in 2009 and is currently working as the technologist for the Linear Power group of Texas Instruments based in Tucson. He was the chip lead of TPS7A02, TI’s first 25nA LDO which is recognized as one of the fastest, smallest, and lowest Iq-power management regulators on the market.
