7 / 14 page 2003 Feb 05 7 Philips Semiconductors Preliminary specification Full bridge current driven vertical deflection booster TDA4867J Notes 1. If VFB is between 40 and 60 V a decoupling capacitor CFB =22 µF (between pin VFB and pin GND) and a resistor RFB = 100 Ω (between pin VFB and flyback supply voltage) are required (see Fig.6). 2. Differential input current Ii(dif) =IINP − IINN. 3. Input resistance is 500 Ω. 4. Required VP depends on the impedance of the deflection yoke. 5. Deviation of the output slope at a constant input slope. Flyback generator IFB(p-p) maximum current during flyback on pin VFB (peak-to-peak value) −− 2.5 A VFB-OUTA voltage drop during flyback between pin VFB and pin OUTA reverse Idefl = −0.7 A −−2.6 −3V Idefl = −1.25 A −−3.1 −3.9 V forward Idefl = 0.7 A − 5.2 6.1 V Idefl = 1.25 A − 5.7 6.9 V Vth(OUTA) switch-on threshold voltage on pin OUTA VP − 1 − VP +1 V Guard circuit (pin GUARD) VGUARD output voltage guard on; IGUARD = −5mA 56 − V guard off; IGUARD =0 −− 0.4 V IGUARD output current guard on; VGUARD >5V −5 −− mA Vext external voltage for guard function 0 − 6.5 V for power save mode; IGUARD = 0.5 mA 8.2 − 9.5 V SYMBOL PARAMETER CONDITIONS MIN.
