Integrated Circuit
Synchronization Signal Processor For
B/W TV and Small−Sized Color TV
Description:
This device is a bipolar analog integrated circuit designed for mono−chrome 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 in−line package.
The vertical stage reduces the power consumption remarkably by the built−in 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 Built−in vertical power stage remarkably low power vertical defection realized by the built−in
voltage booster.
D Vertical fly−back 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)
