TDA4866

The TDA4866 is designed as one kind of full bridge current driven vertical deflection booster that can be used in 90 degree colour vertical deflection systems for frame frequencies of 50 to 160 Hz. Features of the TDA4866 are:(1)excellent transition behaviour during flyback;(2)guard circuit for screen protection;(3)power supply and flyback supply voltage independent adjustable to optimize power consumption and flyback time;(4)powerless vertical shift;(5)high efficient DC-coupled vertical output bridge circuit;(6)high deflection frequency up to 160 Hz;(7)high linear sawtooth signal amplification;(8)pre-amplifier with different-ial high CMRR current mode inputs;(9)low offsets;(10)fully integrated, few external components.

The absolute maximum ratings of the TDA4866 can be summarized as:(1)supply voltage:0 to 30 V;(2)flyback supply voltage (pin 7):0 to 60 V;(3)flyback supply current:0 to ±1.8 A;(4)input voltage:0 to Vp V;(5)input current:0 to ±5 mA;(6)output voltage:0 to Vp V;(7)output current:0 to ±1.8 A;(8)feedback voltage:0 to Vp V;(9)feedback current:0 to ±5 mA;(10)electrostatic handling voltage:-500 to +500 V;(11)storage temperature:-20 to +150 °C;(12)ambient temper-ature:-20 to +75 °C;(13)junction temperature:-20 to +150 °C.

This TDA4866 consists of a differential input stage, two output stages, a flyback generator, a protection circuit for the output stages and a guard circuit.
