U208B
Open Loop Phase Control Circuit
Description
The integrated circuit, U208B, is designed as a phase control circuit in bipolar technology with internal supply-
voltage monitoring.
As the
voltage is built up, uncontrolled output pulses are avoided by internal monitoring.
Furthermore, it has internal-current and
voltage synchronisation.
It is recommended as a low cost open-loop control.
