This is one example of a circuit that uses the features of the HA16114/120 by operating in
synchronization with a flyback AC/DC converter. Note the following design points concerning the
circuit from the secondary side of the transformer to the SYNC pin of the HA16114/120.
Diode D prevents reverse current. Always insert a diode here. Use a general-purpose switching
diode.
Resistors R

and R

form a voltage divider to ensure that the input voltage swing at the SYNC pin
does not exceed Vref (2.5 V). To maintain operating speed, R
