Switched-Capacitor Technology Enables High-Efficiency Power ConvertersJanuary 07, 2020 by Paul Shepard
Today at CES 2020, Halo Microelectronics announced two new products that utilize switched capacitor architecture to deliver 98% efficiency dc-dc conversion, which outperforms traditional dc-dc converters by up to 10% in efficiency. This higher efficiency significantly reduces the thermal dissipation in mobile devices such as smartphones, thus enabling more power to be delivered to the battery and resulting in a faster charging speed.
With the advent of 5G technology, and the increasing demand for rich content delivery, the battery capacity of smartphones will continue to increase, and faster charging will become an increasingly important feature for enhanced user experience. Halo's market leading products will deliver 2x to 5x faster wireless and wired charging experiences in comparison to previous solutions.
"We are excited to be introducing the HL7221 and HL7225 family of products today. With our solution, Halo is enabling charging speed that was unimaginable for mobile phones in the past," said David Nam, CEO of Halo Micro. "With close collaboration with leading mobile OEM's and battery manufacturers, Halo is poised to deliver a safe and seamless fast charging experience for consumers to enhance their ever-increasing dependency on mobile devices."
