TDA 4814
The TDA 4814 A contains all functions for designing electronic ballasts and switched-mode power
supplies with sinusoidal line current consumption and a power factor approaching 1.
They control a boost converter as an active harmonic filter in a discontinuous (triangular shaped
current) mode with variable frequency.
The output voltage of this filter is regulated with high efficiency. Therefore the device can easily be
operated on different line voltages (110/220 V
AC
) without any switchover.
The on-chip start/stop circuit monitors the lamp generator of electronic ballasts. It starts a self-
oscillating lamp generator and shuts it down in the event of malfunction, e.g. if the lamp is defective.
A typical application is in electronic ballasts, especially when a large number of such lamps are
concentrated on one line supply point.
Besides that a separate driver ground (GND QSIP) is implemented.
