UTC1379 1-CHIP DEFECTION SYSTEM DESCRIPTION LI NEAR I NTEGRATED CI RCUI T The UTC1379 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. 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 DIP-16H 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 BLOCK DIAGRAM V-Osc Control V-Osc V-Vcc Boot Strap Flykack Adjusting Boot Strap 2 V-SYNC signal Input SYNC SEParation Output SYNC SEParation Intput 3 4 5 11 7 TAB 8 VOutput 1 16 15 V-OSC V-AMP SYNC-SEP Fly Back Generator 6 NF H-AFC Input 14 H-AFC H-OSC H-PREDRIVERS REGUALTOR 10 H-Vcc w w w .d sh ta a ee u. 4 CS LTD tYOUW ANG ELECTRONI CO. om c H-AFC Output 13 12 H-Osc Control 9 HOutput 1 www..com UTC1379 Characteristic Vertical Supply Voltage Horizontal Supply Current Vertical output Current Horizontal output Current(pulse) Fly-back generator Output current Operating Temperature Storage Temperature Power dissipation(note) LI NEAR I NTEGRATED CI RCUI T Symbol Vcc I10 I8 I9 I5 Topr Tstg PD ABSOLUTE MAXIMUM RATINGS(Ta=25C ) Value 15 30 -500~+500 -15~+5 -500~+500 -20 to +75 -55 to 155 1.3 Unit V mA mA peak mA mA peak C C W ELECTRICAL CHARACTERISTICS(Ta=25C,Vcc=12V,,I10=12mAunless otherwise specified) Characteristic Recommended Vertical Supply Voltage Horizontal Supply Current Vertical Supply current Vertical supply Current Vertical free Running Frequency Drift of Vertical Free-Running Frequency Symbol Vcc I10 ICC(1) ICC(2) FVO fVO/Vcc fVO/TA Test Condition Min 9.6 6.5 Typ. 12 12 85 12 60 0.8 1.5 Max 14 18 100 20 65 2 2 6.3 550 7.2 16.5 27 2.0 Unit V mA mA mA Hz Hz Hz V mAp-p V kHz us mA Vertical output Center Voltage Vertical Output Current Horizontal Supply Voltage Horizontal free running frequency Horizontal Output Pulse Width Horizontal Output Current Vmid I8 V10 fHO tHPW I9 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,SWB=2 SWB=2 6 55 5.3 450 6.2 15 23 0.8 5.8 500 6.7 15.75 25 1.3 YOUW ANG ELECTRONI CO.
