GENERAL DESCRIPTION TDA8350Q The TDA8350Q is a power circuit for use in 90° and 110° colour deflection systems for field frequencies of 50 to 120 Hz.
The circuit provides a DC driven vertical deflection output circuit, operating as a highly efficient class G system and an East-West driver for sinking the diode modulator current.

A flyback supply voltage of >50 V up to 60 V is allowed in application.
A 220 nF capacitor in series with a 22 Ω resistor (dependent on IO and the inductance of the coil) has to be connected between pin 7 and ground.
The decoupling capacitor of VFB has to be connected between pin 8 and pin 4.
This supply voltage line must have a resistance of 33 Ω (see application circuit Fig.
5).
