Notes
1. A flyback supply voltage of >50 V up to 60 V is allowed in application. A 220 nF capacitor in series with a
   22 resistor (depending 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 6 and pin 3. This supply voltage line must have
   a resistance of 33 (see application circuit Fig.6).
2. IO maximum determined by current protection.
3. Up to VP = 18 V.



Description

The TDA8351 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.
