Integrated Circuit
Synchronization Signal Processor For
B/W TV and SmallâSized Color TV
Description:
This device is a bipolar analog integrated circuit designed for monoâchrome TV and small size color
TV. It contains synchronous signal separator, vertical deflection signal generator, vertical power
stage, and horizontal defection signal generator in a molded 16 pins dial inâline package.
The vertical stage reduces the power consumption remarkably by the builtâin voltage booster circuit.
The horizontal signal part can take the working power from any voltage power supply higher than 8
volts, as it equips shunt type power regulator itself. So, it can take the power even from 110 volt power
line through only one resistor.
Features:
D Builtâin vertical power stage remarkably low power vertical defection realized by the builtâin
voltage booster.
D Vertical flyâback pulse width is freely adjustable by the exclusive
D Any supply voltage is available for the horizontal part, as it equips shunt type power regulator
itself.
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
