Flyback with multiple outputs
The schematic of a flyback converter can be seen in Fig. 1. It is equivalent to that of a buck-boost converter, with the inductor split to form a transformer. Therefore, the operating principle of both converters is very similar: • When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source. The primary current and magn… WebFlyback controllers UCC28780 1-MHz High Frequency Active Clamp Flyback Controller Data sheet UCC28780 High Frequency Active Clamp Flyback Controller datasheet (Rev.

WebFlyback transformers are the most popular choice for cost-effective, high-efficiency isolated power supply designs up to approximately 120 Watts. They provide circuit isolation, the potential for multiple outputs and the … Webused in a flyback converter – although commonly referred to as a transformer – behaves as a coupled inductor, combining the functions of energy storage, energy transfer and isolation. Eliminating the need for a separate LC filter on each output greatly reduces the overall cost of multiple output designs. Cost alone makes flyback converters a
