Ramp-generator - vertical pulses from the oscillator is a square, ramp-function generator to change the shape of the signal box into a sawtooth shape. Sawtooth signal shape is determined by the value of resistor-capacitor filter contained in this section.
Vertical count-down circuit and the ramp-generator circuit is in common IC. But there are certain circuits where the ramp generator IC is in the vertical-out, ie aircraft using the TA8690 and TA8445.
Vertical amplifier Drive - serves to amplify the signal before it is fed into the vertical vertical-output amplifier. Circuits generally be one with a vertical power amplifier out.
Vertical power-amplifier Out - vertical sawtooth signal is amplified by this section to be able to supply power to the coil current sawtooth vertical deflection. The working principle of the vertical amplifier-out does not vary much with the audio power-amplifier
Pump Up (flyback generator) - applying localized electron beam vertically from the top to the bottom of the screen. To conduct further re-sweeping the electron beam must be returned with a quick way into the top layer. To do this required a strong pulse but only a moment the so-called vertical-retrace pulse, which pulse is required to establish a higher voltage supply on the vertical-out amplifier.
While doing the sweeping-vertical from the top of the screen to the bottom of the screen vertically-out circuit generally requires a voltage supply of about 25V. And at the vertical-retrace or back from the bottom to the top of the screen quickly takes a larger supply voltage of about 50V. Vertical pump-up circuit is in the vertical IC-out and serves to generate a high voltage at the moment-vertical retrace and require external components consisting of a diode and an Elko.
Vertical-drive circuit, pump-up and reinforcing vertical-out is generally a single IC package in the vertical-out.
There are several types of vertical IC-outs that do not use a pump-up circuit. Instead of the vertical-out requires two kinds of supply Vcc, the supply of low voltage and high voltage supply.
