Overview
TECHNICAL DATA DC-COUPLED VERTICAL DEFLECTION CIRCUIT 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 (thermal) protection High EMC immunity because of common mode inputs A guard signal in zoom mode.
GENERAL DESCRIPTION The ILA8351 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.

com Note 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 6 and pin 3.
The supply voltage line must have a resistance of 33 Ω.
