.@onsemi Eval board's high-density QR flyback converter enables advanced power-supply designs

Environmental regulations now in place have major implications when it comes to implementing modern power-system designs. Government bodies in both North America and Europe are enforcing measures that mean efficiency levels must be improved significantly. For example, updates to the European Code of Conduct mean that if a 40-W power supply is to comply with the minimum average efficiency, then it has to exhibit a 1% better efficiency level than was adequate in 2014. In addition, there’s another crucial factor coming into play, as OEMs heighten their expectations with regard to power adapters. Since the overall efficiency levels are being improved, power losses are as a result lighter. This means that there’s a provision for adaptor dimensions to be reduced (making them more attractive to end customers). In addition, unit costs can be curbed as smaller, less expensive heat ...
