TCA785 Datasheet (Infineon Technologies)

TCA785, Phase Controller

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
