TCA785 General Description

The synchronization signal is obtained via a high-ohmic resistance from the line voltage (voltage V5). A zero voltage detector evaluates the zero passages and transfers them to the synchronization register. This synchronization register controls a ramp generator, the capacitor C10 of which is charge.
