STV9302B

The STV9302B belongs to STV9302 family, which is a vertical deflection booster designed for TV and monitor applications.This device, supplied with up to 35 V, provides up to 2 App output current to drive the vertical deflection yoke.The internal flyback generator delivers flyback voltages up to 70 V. In double-supply applications, a stand-by state will be reached by stopping the (+) supply alone.

The maim features of STV9302B are (1)power amplifier; (2)flyback generator; (3)output current up to 2 App; (4)thermal protection; (5)stand-by control.

The absolute maximum ratings of STV9302B are (1)VS(supply voltage (pin 2):  Note 1 and Note 2):40 V; (2)V5, V6(flyback peak voltage: Note 2): 70 V; (3)V3,( Voltage at Pin 3: - Note 2, Note 3 and Note 6): -0.4 to (VS + 3) V; (4)V1, V7(amplifier input voltage:  Note 2, Note 6 and Note 7): - 0.4 to (VS + 2) or +40V; (5)I0 (1)(output peak current at f = 50 to 200 Hz, t 10s:  Note 4):±5A; (6)I0 (2)(output peak current non-repetitive:  Note 5):±2 A; (7)I3 sink(sink current, t<1ms):1.5 A; (8)I3 source(source current, t < 1ms:  Note 3): 1.5 A; (9)I3(flyback pulse current at f=50 to 200 Hz, t10s:  Note 4): ±5 A; (10)ESD1(human body model (100 pF discharged through 1.5 k)):2 kV; (11)ESD2(EIAJ Standard (200 pF discharged through 0 )): 300 V; (12)Ts(storage temperature): -40 to 150 °C; (13)Tj(junction temperature): +150 °C.(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-Offphases. This peak current is acceptable providing the SOA is respected (Figure 8 and Figure 9: to see the PDF).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.)
