GENERAL DESCRIPTION
The TDA4800 is an integrated circuit for vertical deflection primarily in monitors (and TV receivers). The complete circuit consists of 11 main functional blocks as shown in Fig.1.

FEATURES
• Fully integrated, few external components
• RC oscillator with wide sync range of 1 : 3 (e.g. 50 to 150 Hz)
• Synchronization by positive or negative going sync pulse
• Blanking pulse duration is determined externally
• Dual frequency criterion for automatic amplitude switch-over (e.g. 50 to 60 Hz)
• Guard circuit for screen protection
• Sawtooth generator with buffer stage supplied by external voltage
• Preamplifier
• Power output stage with thermal and SOAR protection
• Flyback generator
• Internal voltage stabilizer.
