Vertical deflection circuit
Product specification
TDA2653A
DESCRIPTION
The TDA2653A is a monolithic integrated circuit for vertical deflection in large screen colour television receivers.
The circuit incorporates the following functions:
• Oscillator; switch capability for 50 Hz/60 Hz operation
• Synchronization circuit
• Blanking pulse generator with guard circuit
• Sawtooth generator with buffer stage
• Preamplifier with fed-out inputs
• Output stage with thermal and short-circuit protection
• Flyback generator
• Voltage stabilizers
