L6565D Quasi-Resonant SMPS Controller/Switch Controller IC Soic- 8, TV/Monitor/Scanner/Fax Machine/Photocopier

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