Notes, cont.

(11) Other input or output voltage ranges will be reviewed under scheduled quantity special order.

(12) Maximum PC board temperature is measured with the sensor in the center of the converter.

(13) Do not exceed maximum power speciﬁ cations when adjusting the output trim.

(14) The maximum output capacitive loads depend on the the Equivalent Series Resistance (ESR) of the external

output capacitor and, to a lesser extent, the distance and series impedance to the load. Larger caps will reduce

output noise but may change the transient response. Newer ceramic caps with very low ESR may require lower

capacitor values to avoid instability. Thoroughly test your capacitors in the application. Please refer to the Output

Capacitive Load Technical Note.

(15) Do not allow the input voltage to degrade lower than the input undervoltage shutdown voltage at all times.

Otherwise, you risk having the converter turn off. The undervoltage shutdown is not latching and will attempt to

recover when the input is brought back into normal operating range.

(16) The outputs are not intended to sink appreciable reverse current.

(17) “Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output. If the

overcurrent condition still exists, the restart current will be removed and then tried again. This short current pulse

prevents overheating and damaging the converter. Once the fault is removed, the converter immediately recovers

normal operation.
