UTC1031
LINEAR INTEGRATED CIRCUIT
TV VERTICAL DEFLECTION
SYSTEM
DESCRIPTION
The UTC1031 is a monolithic integrated circuit
designed for use in the vertical deflection circuit of
monochrome and small color television receivers. It
oscillates vertical synchronizing with the vertical
synchronization signal and outputs the vertical
deflection current with a single chip.
FUNCTIONS
*Vertical synchronization circuit
*Vertical oscillation circuit
*Vertical saw-tooth shape
*Vertical output circuit
*Clamping circuit for blanking pulse
*Temperature compensating circuit
FEATURES
*Less number of external components
*Wide operating voltage
*Freely adjustable pull-in range
*Large output current-capacity
*Built-in adjusting circuit for fly back time.
