He then proposes a high efficiency solution where a MOSFET, controlled by the MAX17606 synchronous MOSFET driver, replaces the secondary-side diode.

How to optimise the efficiency performance of a flyback converter
In this video from Maxim Integrated, Furqan explains why a Discontinuous Conduction Mode (DCM) flyback converter, using a secondary-side rectification diode, is unsuitable for low voltage high current applications.
