In USB and isolated low power converter designs-quasi resonant and discontinuous conduction mode flyback converter topologies are a popular choice, due to their low parts count and relatively low cost. To reduce the cost even further, TI has developed a quasi-resonant/discontinuous current mode flyback controller with primary-side control. - Troubleshooting TI PSR controllersPDF, 6.5 Mb, Archivo publicado: oct 3, 2016
