DESCRIPTION
The L6565 is a current-mode primary controller IC,
specifically designed to build offline Quasi-resonant
ZVS (Zero Voltage Switching at switch turn-on) fly-
back converters.
Quasi-resonant operation is achieved by means of a
transformer demagnetization sensing input that trig-
gers MOSFET's turn-on.
