Use this utility to find the perfect part for your solution. » ISOdrivers Parametric Search Featured White Papers When to Use a Digital Isolator vs. an Optocoupler Over the last four decades, optocouplers have been the "default" signal isolation device, but recent breakthroughs in silicon isolation technology have spawned smaller, faster, and more reliable and cost-effective solutions that have already begun supplanting optocouplers in many end applications. This white paper discusses industrial isolation issues and ways RF isolation technology can be applied to increase system robustness and performance. » When to Use a Digital Isolator vs. an Optocoupler Enhancing Power Delivery System Designs with CMOS-Based Isolated Gate Drivers As emerging green standards challenge designers to deliver more energy-efficient, cost-effective and reliable power delivery systems in smaller form factors, the need for greater power and isolation device integration becomes increasingly important. A critical building block within ac-dc and isolated dc-dc power supplies is the isolated gate driver. While optocoupler-based solutions and gate-drive transformers have been the mainstay for switch-mode power supply (SMPS) systems for many years, fully-integrated isolated gate driver products based on RF technology and implemented in mainstream CMOS provide a more reliable and power-efficient solution. » Enhancing Power Delivery System Designs with CMOS-Based Isolated Gate Drivers View all Isolation and Power Training & Resources...
