STMicroelectronics L6567 Manuals

The L6567 is a monolithic high voltage integrated circuit designed by STMicroelectronics to drive CFL and small TL lamps with a minimum number of components. It provides all the necessary functions for proper preheating, ignition and steady state operation of the lamp, such as variable frequency oscillator, settable preheating and ignition time, capacitive mode protection, and lamp power independent from mains voltage variation. In addition to the control functions, the IC provides the level shift and drive function for two external power MOS FETs in a half-bridge topology.

This document introduces a high voltage driver called L6567, which is used for driving CFL and small TL lamps. It features a variable frequency oscillator, settable preheating and ignition time, capacitive mode protection, etc.

L6567 is a high voltage driver designed to drive CFL and small TL lamps with 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.
