Notas de aplicación
- UCC28700 5-W USB Flyback Design Review (Rev. C)PDF, 466 Kb, Revisión: C, Archivo publicado: feb 21, 2014
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 in these designs TI has developed a quasi-resonant/discontinues current mode flyback controller with primary side control. - Troubleshooting TI PSR controllersPDF, 6.5 Mb, Archivo publicado: oct 3, 2016
