TDA1175 LOW-NOISE VERTICAL DEFLECTION SYSTEM . . . . COMPLETE VERTICAL DEFLECTION SYSTEM LOW NOISE SUITABLE FOR HIGH DEFINITION MONITORS ESD PROTECTED DESCRIPTION The TDA1175 is a monolithic integrated circuit in FINDIP plastic package. It is intended for use in black and white and colour TV receivers. Low-noise makes this device particularly suitable for use in monitors. The functions incorporated are : synchronization circuit, oscillator and ramp generator, high power gain amplifier, flyback generator, voltage regulator.
