Philips Semiconductors
DC-coupled vertical deflection and
East-West output circuit
Preliminary specification
TDA8350Q
FEATURES
• Few external components
• Highly efficient fully DC-coupled vertical output bridge
circuit
• Vertical flyback switch
• Guard circuit
• Protection against:
– short-circuit of the output pins
– short-circuit of the output pins to VP
• High EMC immunity due to common mode inputs
• Temperature (thermal) protection
• East-West output stage with one single conversion
resistor.
GENERAL DESCRIPTION
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.

Note
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 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).
