Power Integrations Inc of San Jose, CA, USA (which provides high-voltage integrated circuits for energy-efficient power conversion) has introduced a flyback topology that extends the power range of flyback converters to 440W — well beyond the limits that traditionally required more complex resonant and LLC topologies. The new TOPSwitchGaN flyback IC family unites the company’s PowiGaN technology with its TOPSwitch IC architecture, reducing complexity, eliminating heat-sinks in many cases, shortening design time, improving manufacturability, and lowering total system cost...
