PC1379
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
1-CHIP DEFECTION SYSTEM
The Contek PC1379 consists of a vertical system, including function and a horizontal system, including an AFC function.
It is for use in small size color TVs, B/W TV receivers and monitors.
FEATURES
*Low power consumption, direct deflection coil driving capability(Fly-back voltage two times as high supply voltage is supplied during fly-back period only) *Variable circuit of vertical retrace time on chip
FUNCTIONS
HORIZONTAL SECTION
*SYNC separation *Horizontal Oscillators *Horizontal Pre-drivers *Horizontal AFCs *Shunt Regulator(Typical 6.
7V)
DIP-16H
VERTICAL SECTION
*Vertical Oscillator *Vertical Pre-drivers *Vertical Output *Fly-back generators
