| UTC PC1379 DESCRIPTION LINEAR INTEGRATED CIRCUIT 1-CHIP DEFECTION SYSTEM 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 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 V-OSC 8 VOutput 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 UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R111-005,A UTC PC1379 PARAMETER Vertical Supply Voltage Horizontal Supply Current Vertical Output Current Horizontal Output Current(pulse) Fly-back Generator Output Current Operating Temperature Storage Temperature Power Dissipation LINEAR INTEGRATED CIRCUIT SYMBOL VCC I10 I8 I9 I6 Topr Tstg PD ABSOLUTE MAXIMUM RATINGS(Ta=25C) VALUE 15 30 -500 ~ +500 -15 ~ +5 -500 ~ +500 -20 ~ +75 -55 ~ +155 1.3 UNIT V mA ma peak mA ma peak C C W ELECTRONICAL CHARACTERISTICS(Ta=25C,VCC=12V,I10=12mA, unless otherwise specified) PARAMETER Recommend Vertical Supply Voltage Horizontal Supplu Current Vertical Supply Current Vertical Supply Current Vertical Free Running Frequency Drift of Vertical Free Running Frequency Fvo/Ta Vertical Output Center Voltage Vertical Output Current Horizontal Supply Voltage Horizontal Free Running Frequency Horizontal Output Pulse Width Horizontal Output Current Vmid IB V10 FHO THPW I9 SYMBOL Vcc I10 Icc(1) Icc(2) Fvo Fvo/Vcc SWA=2 No Input Signal, SWA=2 SWA=1 Fvo=Fvo(14.4V)-Fvo(9.6V) SWA=2 Fvo=Fvo(-20C)-Fvo(70C) SWA=2 SWA=2 SWA=2 SWB=2 I10=12mA SWB=1 FHO=15. 75KHZ.
