PREHEAT AND FREQUENCY SHIFT TIMING
DESCRIPTION
The device is a monolithic high voltage integrated cir-
cuit designed to drive CFL and small TL lamps with a
minimum part count.
It provides all the necessary functions for proper pre-
heat, 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 lev-
elshift and drive function for two external power MOS
FETs in a half-bridge topology.
