LIN-IC/9-SIL
The
Full bridge current driven vertical deflection booster
TDA4867J is a p
o
wer booster for use in colour vertical
deflection systems for frame frequencies of 50 to 200 Hz.The circuit provides a high CMRR current drivendifferential input. Due to the bridge configuration of the twooutput stages DC-coupling of the deflection coil isachieved. In conjunction with the deflection controllerfamily TDA485x and SAA4856 the ICs offer an extremelyadvanced system solution.QUICK REFERENCE DATANotes1. Voltages refer to pin GND.2. If VFB is between 40 and 60 V a decoupling capacitor CFB=22μF (between pin VFB and pin GND) and a resistorRFB= 100Ω (between pin VFB and flyback supply voltage) are required (see Fig.6).3.
