DESCRIPTION  
2000 COMPLIANT  
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.  
APPLICATIONS  
TV/MONITOR SMPS  
AC-DC ADAPTERS/CHARGERS  
DIGITAL CONSUMER  
Quasi-resonant operation is achieved by means of a  
transformer demagnetization sensing input that trig-  
gers MOSFET's turn-on.
