UTC PC1379 LINEAR INTEGRATED CIRCUIT UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R111-005,A 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 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 BLOCK DIAGRAM V-AMP REGUALTORH-PREDRIVERSH-OSCH-AFC SYNC-SEP V-OSC Fly Back Generator 2 3 5 114 7 91213 V-Osc Control V-Osc V-Vcc Boot Strap NF Boot Strap Output Output Flykack Adjusting H-Osc Control H-Vcc H-AFC Output H.AFC Input SYNC SEParation Input SYNC SEParation Output
