Although this scheme works well, bandwidth limitations usually restrict these circuits to operation below 100kHz. Figure 50 shows the LT1016 comparator in an open-loop, synchronous rectifier configuration which has high accuracy out to 2.5MHz. An input 1MHz sine wave (Trace A, Figure 51) is ze...

The collapsing magnetic field induces a change in voltage across the transformer's windings. During this transition the Switch pin's voltage flies to 10.6V plus a diode above V+, the secondary forward biases the rectifier diode D2 and the transformer's energy is transferred to VBOOST. ...
