U208 BTELEFUNKEN SemiconductorsRev. A1, 28-May-961 (7) open Loop Phase Control CircuitDescriptionThe integrated Circuit , U208B, is designed as a Phase con-trol Circuit in bipolar technology with internalsupply-voltage monitoring. As the voltage is built up, un-controlled output pulses are avoided by internalmonitoring. Furthermore, it has internal-current and volt-age synchronisation. It is recommended as a low costopen-loop retriggeringDTriggering pulse typ. 125 mADVoltage and current synchronisationDInternal supply voltage monitoringDCurrent requirement mAPackage: DIP8 Block Diagram236N95 11224R3220 kW/R4470 kW/ VS10 nFGNDC122 mF/25 VR7180 WMR118 kW/BYT77D12 WTICLNVM =230 V ~SupplyvoltagelimitationOutputpulsePhase Control unit521 VoltagedetectorAutomaticretriggering783= f (V6)C2100 WR2180 kWR618 kWR5120 kW46 Figure 1.
