WebThe flyback topology (Figure 1A) results in significant cost and space savings for multiple output power supplies with high output voltage for power levels up to 100W. This topology uses a transformer, which is essentially a coupled inductor with multiple windings on the same magnetic core. WebFlyback converter topology is shown in Fig. 4.1. It is very widely used for output powers from about 150 down to under 5 W. Its great initial attraction-although it is not strictly so, … WebThe LT3748 is a switching regulator controller specifically designed to simplify the design of isolated power supplies using a flyback topology. No third winding or opto-isolator is required as the LT3748 senses the isolated output voltage directly from the primary-side flyback waveform. horses business
