Description

The L6567 is a monolithic high voltage integrated circuit designed to drive CFL and small TL lamps with a minimum part count.

L6567 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.
