Internet of Things (IoT)
Billions of offline powered "smart things" with embedded intelligence, such as sensors, actuators, and connectivity, will support the rapid growth of IoT in the near future. The significant impact on worldwide energy consumption from these "always-connected" products has driven the need for compact, highly efficient offline power converters with ultra-low standby power consumption.
Power Integrations offers a broad range of integrated high-voltage ICs to power Smart Home and Building Automation devices most efficiently from the AC mains. These ICs integrate power MOSFETs and control and protection circuitry on a single chip; this enables customers to design low component count solutions with fast time to market. Some key benefits are dramatic reduction in standby energy waste by EcoSmart™ technology, elimination of typical opto-couplers with an innovative FluxLink™ technology for feedback across an isolation barrier, reduced EMI with frequency jitter, fault protection, and improved reliability with built-in thermal shutdown.
