NTE1661 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.
