Philips Semiconductors
DC-coupled vertical deflection circuit
Product specification
TDA8351
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 (7 and 4)
– short-circuit of the output pins to VP
Temperature protection
High EMC immunity because of common mode inputs
A guard signal in zoom mode.
GENERAL 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.

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 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).
