TDA4861 Vertical deflection power amplifier

TDA4861 The TDA4861 is a vertical power amplifier for differential input signals suitable for colour monitor/TV systems with deflection frequencies up to 140 Hz. MAX. 30 60 60 10 − 2.8 +75 V V V UNIT mA mA A °C VP1 − 0.5 V ORDERING INFORMATION TYPE NUMBER TDA4861 PACKAGE NAME SIL9P DESCRIPTION plastic single in-line power package; 9 leads VERSION SOT1.

Features

• Vertical pre-amplifier with differential inputs
• Powerless vertical shift
• Flyback voltage generation suitable for two operating modes (doubling the supply voltage or external supply for the short flyback time, this achieves a minimum of power dissipation)
• Vertical output stage with thermal and SOAR protection
• High deflection frequency up to 140 Hz
• High linear sawtooth signal amplification
• Possibility of guarding the deflection
• Voltage stabilizer. QUICK REFERENCE DATA Measurements referenced to substrate (pin 6). SYMBOL VP1 VP2 VP3 IP1 IP2 VI I5(p-p) Tamb supply voltage (pin 1) s.
