1 Absolute Maximum Ratings
Note:1. Usually the flyback voltage is slightly more than 2 x V
S
. This must be taken into consideration when
setting
V
S.
2. Versus pin 4
3. V3 is higher than V
S
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 V
S
+ 2 or 40 volts.
