TDA8178

The TDA8178 is a kind of TV vertical deflection booster. It is designed for monitors and high performance TVs. It delivers flyback voltages up to 105 V. It operates with supplies up to 50 V and provides up to 2App output current drive to yoke. It is available in HEPTAWATT package.

There are some features of TDA8178 as follows: (1)power amplifier; (2)flyback generator (105 V peak); (3)thermal protection; (4)reference voltage; (5)current limited to GND.

The following is about the absolute maximum ratings about TDA8178: (1)VS, supply voltage (pin 2): 50 V; (2)V5, V6, flyback peak voltage: 105 V; (3)V1, V7, amplifier input voltage: +VS V; (4)IO, output peak current (non repetitive, t=2 ms): 2 A; (5)IO, output peak current at f=50 or 60 Hz, t10s: 2 A; (6)IO, output peak current at f=50 or 60 Hz, t>10s: 2 A; (7)I3, pin 3 DC at V5
