Philips TDA1170 Service Manual
LOW-NOISE TV VERTICALDEFLECTIONSYSTEM
.
COMPLETE VERTICAL DEFLECTION SYSTEM
.
LOW NOISE
.
SUITABLE FOR HIGH DEFINITION MONITORS
DESCRIPTION
The TDA1170Dis a monolithicintegratedcircuitin
a 16-leaddualin-line plasticpackage.Itis intended
for use in black and whiteandcolourTV receivers.
Low-noise makes this deviceparticularly suitable for use in monitors. The functions incorpo-
rated are : synchronization circuit, oscillator and
ramp generator,highpower gain amplifier,flyback
generator,voltageregulator.
