PC1379 LINEAR INTEGRATED CIRCUIT 1-CHIP DEFECTION SYSTEM DESCRIPTION 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 DIP-16H 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 BLOCK DIAGRAM 1 SYNC SEParation Output 16 SYNC SEParation Input 15 H.AFC Input 14 V-Osc Control V-Osc V-Vcc Boot Strap 2 3 4 5 Flykack Adjusting 11 V-OSC 7 Contek V-AMP 8 VOutput 6 NF Fly Back Generator SYNC-SEP H-AFC Boot Strap H-OSC H-PREDRIVERS REGUALTOR 13 12 9 H-AFC Output H-Osc Control HOutput 10 Contek Microelectronics Co.,Ltd.
