Description
Designed for TV applications, the OPTIMWATTTM
STV9382 is a Class-D vertical deflection booster
assembled in a 20-pin plastic DIP package.
It belongs to the OPTIMWATTTM Class-D vertical
deflection booster family.
It operates with supplies up to ±18 V and provides
an output current up to 1.5 APP to drive the yoke.
The internal flyback generator avoids the need for
an extra power supply.

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.
