OPTIMWATTTM STV9382

Electrical Characteristics

TAMB = 25° C, VCC = ±12 V and fVERT = 50 Hz unless otherwise specified (refer to Figure 1)

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. VCC ripple =1 VPP and 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 1.5 APP . The corresponding power dissipated in the vertical deflection

yoke is 1.7 W.
