UTC PC1379 LINEAR INTEGRATED CIRCUIT 1-CHIP DEFECTION SYSTEM DESCRIPTION The UTC 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 UTC V-Osc Control V-Osc V-Vcc Boot Strap 2 3 4 5 Flykack Adjusting 11 V-OSC 7 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 H-Vcc UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R111-005,A UTC PC1379 LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS(Ta=25°C) PARAMETER SYMBOL VALUE VCC 15 V I10 30 mA Vertical Output Current I8 -500 ~ +500 ma peak Horizontal Output Current(pulse) I9 -15 ~ +5 mA Fly-back Generator Output Current I6 -500 ~ +500 ma peak Vertical Supply Voltage Horizontal Supply Current UNIT Operating Temperature Topr -20 ~ +75 °C Storage Temperature Tstg -55 ~ +155 °C PD 1.3 W Power Dissipation ELECTRONICAL CHARACTERISTICS(Ta=25°C,VCC=12V,I10=12mA, unless otherwise specified) MIN TYP MAX Recommend Vertical Supply Voltage PARAMETER SYMBOL Vcc TEST CONDITIONS 9.6 12 14 V Horizontal Supplu Current I10 6.5 12 18 mA 85 100 mA 12 20 mA Vertical Supply Current Icc(1) SWA=2 Vertical Supply Current Icc(2) No Input Signal, SWA=2 6 Fvo SWA=1 55 Fvo/Vcc Fvo=Fvo(14.4V)-Fvo(9.6V) Vertical Free Running Frequency Drift of Vertical Free Running Frequency UNIT 60 65 Hz 0.8 2 Hz 1.5 2 Hz SWA=2 Fvo/Ta Fvo=Fvo(-20°C)-Fvo(70°C) SWA=2 Vertical Output Center Voltage Vertical Output Current Vmid SWA=2 5.3 5.8 6.3 V IB SWA=2 450 500 550 mAp-p SWB=2 6.2 6.7 7.2 V 15 15.75 16.5 KHZ Horizontal Supply Voltage V10 Horizontal Free Running Frequency FHO Horizontal Output Pulse Width Horizontal Output Current UTC I10=12mA SWB=1 THPW FHO=15. 75KHZ.
