Question:
At start-up of S-8323~4, a large peak current flows through the CONT terminal. Is it possible that the
peak current could cause a loss that exceeds the power dissipation
Answer:
The power dissipation for S-8323~4 is 500 mW when the SOT-89 package is used, and 150 mW when
the SOT-23 package is used. However, these power dissipation are only applicable when the loss is
steady. At start-up, the large peak current at the CONT terminal lasts only until the output voltage
increases to the preset value. Based on actually measured data using the SOT-23 package, the power
dissipation for the peak current duration (tpk) at the CONT terminal is shown in the figure below. For
example, when the peak current duration (tpk) at the CONT terminal is 100 m SEC, the power
dissipation is up to 5 W; the peak current is up to 1 A if CONT=5 V.
