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