STV9380A

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 , 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 APP. The corresponding power dissipated in the vertical deflection

yoke is 2.8 W.
