L6565N General 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) flyback converters.
Quasi-resonant operation is achieved by means of a transformer demagnetization sensing input that triggers MOSFET's turn-on.

L6567 General Description
The device is a monolithic high voltage integrated circuit designed to drive CFL and small TL lamps with a minimum part count.
It provides all the necessary functions for proper preheat, ignition and steady state operation of the lamp:
· variable frequency oscillator;
· settable preheating and ignition time;
· capacitive mode protection;
· lamp power independent from mains voltage variation.
Besides the control functions, the IC provides the level shift and drive function for two external power MOS FETs in a half-bridge topology.
