Note 1. Input voltage = 0, measured after the filter (e.g. across the 470 nF filter capacitor)
2. Supply rejection of the positive or negative power supply. V_CC ripple =1 V_PP , f =100 Hz, measured
on the sense resistor.
3. Power dissipated in the circuit in the case of the application from Figure 1 and the current in the
deflection yoke adjusted to 2.5 A_PP. The corresponding power dissipated in the vertical deflection
yoke is 2.8 W.
