TV VERTICAL OUTPUT CIRCUIT
9-SIPH
The KA2131 is a monolithic integrated circuit designed for the vertical output stage in color television receivers.
FUNCTIONS
Driver stage. Output stage. Flyback generators. Pulse shapers.
FEATURES
Low power consumption, direct deflection coil driving capability (Flyback voltage is two times as high as the supply voltage is supplied during flyback period only). High breakdown voltage: 60V. ORDERING INFORMATION Device Package Operating Temperature KA2131 9-SIPH -20°C ~+70°C
