Philips Semiconductors
Vertical deflection power amplifier for
monitors
FEATURES
Vertical pre-amplifier with differential inputs
Powerless vertical shift
Flyback voltage generation suitable for two operating
modes (doubling the supply voltage or external supply
for the short flyback time, this achieves a minimum of
power dissipation)
Vertical output stage with thermal and SOAR protection
High deflection frequency up to 140 Hz
High linear sawtooth signal amplification
Possibility of guarding the deflection
Voltage stabilizer.
QUICK REFERENCE DATA
