CONTEK PC1379 Datasheet
PC1379 LINEAR INTEGRATED CIRCUIT
1-CHIP DEFECTION SYSTEM
DESCRIPTION
The Contek
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
PC1379 consists of a vertical system, including
FUNCTIONS
HORIZONTAL SECTION
*SYNC separation
*Horizontal Oscillators
*Horizontal Pre-drivers
*Horizontal AFCs
*Shunt Regulator(Typical 6.7V)
VERTICAL SECTION
*Vertical Oscillator
*Vertical Pre-drivers
*Vertical Output
*Fly-back generators
