Overview
LINEAR INTEGRATED CIRCUIT VERTICAL DEFLECTION CIRCUIT PRELIMINARY DATA The TDA 1770 is a monolithic integrated circuit in 20-lead plastic package.
It is a full performance and very efficient vertical deflection circuit intended for direct drive of the yoke.
It offers a wide range of applications in portable CTVs, BW TVs, monitors and displays.
The functions incorporated are: synchronization circuit.
precision oscillator and ramp generator power output amplifier fly back generator voltage regulator precision blanking pulse generator thermal shut down protection CRT screen protection circuit which blanks the beam current in the event of loss of vertical deflection current.
The TDA 1770 is assembled in a new 20-lead plastic package which has 4 centre pins connected together and used for heatsinking.
