Power Product of the Year
Product Name: InnoSwitch™3-TN family of ICs
Company: Power Integrations
With energy prices at an all-time high and a pressing agenda to reduce global energy consumption, it has never been more important to ensure efficient energy usage. Power Integrations is a recognised leader in high-performance components for power conversions and its ICs are used in numerous electronic products ranging from smartphones to high-power solar energy systems. Since 1998, the company’s EcoSmart™ energy-efficiency technology has prevented billions of pounds of energy waste and millions of tons of carbon emissions.
Power Integrations’ InnoSwitch™3-TN family of ICs dramatically increases the efficiency of auxiliary power supplies used in appliances, consumer products and industrial applications. It is a high-efficiency off-line CV/CC QR Flyback switcher IC, ideal for isolated and non-isolated applications that reduces energy waste in appliance power supplies by up to 75%.
Designed to simplify the design of power supplies, InnoSwitch3-TN ICs are aimed at appliance and industrial auxiliary applications up to 21W. They support the high output current needed in smart-connected appliances at up to 90% efficiency compared to traditional design approaches such as buck regulators. InnoSwitch3-TN devices incorporate all feedback components while supporting isolated, non-isolated, single and multi-output designs for the most compact, flexible auxiliary power supply solution.
The devices have an integrated 725V primary MOSFET, synchronous rectification and integrated secondary-side control and are packaged in a safety-qualified, compact MinSOP™-16A package, which reduces PCB area. In addition, fewer external components are required than with alternative design approaches. The advanced InnoSwitch3-TN flyback controller delivers constant efficiency across the load range and less than 5mW no-load consumption. The flexibility afforded by Power Integrations’ proprietary FluxLink™ communication technology means that positive and negative outputs are easily achieved. InnoSwitch3-TN ICs can be used in a 5 V single-output power supply, with two positive output rails, or with both positive and negative rails, without any external feedback components. Safety-rated FluxLink technology also ensures reliable synchronous rectification and accurate constant voltage and constant current on the output. The low forward drop of the SR MOSFET also ensures excellent cross-regulation performance.
The devices feature a comprehensive range of safety features including output over-current and over-temperature protection.
In summary, InnoSwitch™3-TN ICs bring simplicity to power supply design, combined with an outstanding ability to reduce energy wastage, helping to achieve a greener and more energy-efficient planet.
