The specifications of the flyback diode should, at a minimum, double those values: a continuous forward current (I f) of at least 0.478 A with a peak inverse voltage (PIV) rating of 180 V.

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or ...

Although the circuit of Figure 1 targets use in a 7W, single-output requirement, this synchronous flyback circuit applies to a wider power range; you can easily extend it to multiple outputs by adding ...

Here is a simple, compact circuit for isolating a low power –48V output. The gyrator circuit allows AC signals to ride on the DC output voltage, adding audio signaling capability for communications ...

A half-bridge flyback topology, using a rectifier diode that connects the gate of the high-side MOSFET to the bus (Fig. 2, again), offers a better alternative to the conventional approach.
