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.
