1 / 11 page 1/11 April 2004 TEA2031A COLOR TV EAST-WEST CORRECTION REV. 2 FEATURES SUMMARY ■ BUILD IN FRAME PARABOLA FROM EXTERNAL SAW-TOOTH ■ PARABOLA CORRECTION ADJUSTMENT ■ KEYSTONE CORRECTION ADJUSTMENT ■ LINE SIZE ADJUSTMENT ■ LINE DYNAMIC CORRECTION POSSIBILITY (beam current) ■ D CLASS OUTPUT MODULATOR WITH BUILD IN RECOVERY DIODE ■ 50 OR 60Hz OPERATION ■ LOW DISSIPATION ■ FEW EXTERNAL COMPONENTS DESCRIPTION The TEA2031A is intended to ensure frame rate modulated parabolic and keystone corrections to the horizontal deflection circuitry of 110 ° color TV sets. The linear frame saw-tooth is applied to appropri- ate circuitry from which a corresponding parabolic waveforms is obtained. This waveform is then fed to a comparator together with the linear line saw- tooth for comparison. Comparator’s output drives the output power stage which is capable of sinking the external coil currents of up to 0.5A. An internal recovery diode feeds back to the power supply the coil fly-back current pulses of as high as 0.5A. Figure 1. Package 8 1 DIP8 (Plastic Package) |
