The InnoSwitch family is Power Integrations' flagship AC-DC converter series featuring integrated synchronous rectification and FluxLink feedback technology. Key benefits include: 1) Highest efficiency up to 94% eliminating heatsinks, 2) Integrated 750V or 900V MOSFET for excellent surge protection, 3) FluxLink technology eliminates optocoupler improving reliability, 4) Excellent cross-regulation for multi-output designs, 5) Comprehensive protection features. Use InnoSwitch for applications requiring highest efficiency, compact size, and excellent reliability such as high-end adapters, industrial power supplies, and appliance power.

Choose InnoSwitch for designs prioritizing efficiency and compact size. Contact our FAE team for design optimization assistance.

What is the difference between LinkSwitch and TOPSwitch families?

LinkSwitch and TOPSwitch are both Power Integrations' AC-DC converter families but target different power levels: LinkSwitch is designed for low-power applications from 1W to 15W, featuring simple design with minimal external components, excellent for cost-sensitive applications like mobile chargers and small appliances. TOPSwitch handles higher power from 10W to 250W, offering higher efficiency, better thermal performance, and more advanced features like frequency jittering for EMI reduction. TOPSwitch is suitable for laptop adapters, LCD TV power, and industrial power supplies.

Use LinkSwitch for low-power cost-sensitive designs under 15W, and TOPSwitch for higher power applications up to 250W requiring better efficiency.
