A Complete Monolithic Vertical-Deflection System for Television

A one-chip TV vertical deflection system is now possible through recent advances in power IC technology. This paper describes the new integrated circuit which includes the vertical oscillator, output stage, and a special flyback generator. The temperature stable sawtooth oscillator has independent hold and height controls and is capable of excellent interlace. A current drive output stage precludes the need for a linearity control or yoke thermistor while providing the versatility to directly drive black and white through large screen color yokes. The advanced output flyback system provides excellent flyback and blanking from low supply voltages.
