Description
The STV9326 is a vertical deflection booster
designed for TV and monitor applications.
This device, supplied with up to 30 V, provides up to
3 App output current to drive the vertical deflection
yoke.
The internal flyback generator delivers flyback
Tab connected
voltages up to 65 V.

Note:1. Usually the flyback voltage is slightly more than 2 x VS. This must be taken into consideration when

setting VS.

2. Versus pin 4

3. V3 is higher than VS during the first half of the flyback pulse.

4. Such repetitive output peak currents are usually observed just before and after the flyback pulse.
5. This non-repetitive output peak current can be observed, for example, during the Switch-On/Switch-

Off phases. This peak current is acceptable providing the SOA is respected (Figure 8 and Figure 9).

6. All pins have a reverse diode towards pin 4, these diodes should never be forward-biased.

7. Input voltages must not exceed the lower value of either VS + 2 or 40 volts.

8. In normal applications, the peak flyback voltage is slightly greater than 2 x (VS — V4). Therefore, (VS

— V4) = 30 V is not allowed without special circuitry.

9. Refer to Figure 4, Stand-by condition.
