DESCRIPTION
Designed for monitors and TVs, the STV9381 is a
class-D vertical deflection booster assembled in
PDIP20 Package.
It operates with supplies up to +/- 18V, provides
up to 3 App output current to drive the yoke. The
internal flyback generator avoids the need for an
extra power supply.

Note: 2 Input voltage = 0, measured after the filter (e.g. accross the 470 nF filter capacitor)
Note: 3 Supply rejection of the positive or negative power supply. Vcc ripple =1Vpp, f=100Hz, measured on the sense
resistor.
