Speci?cation Notes, Cont.:
(7)
(8)
(9)
Please observe the voltage input and output speci?cations in the Voltage Range Graph on page 17.
Output noise may be further reduced by adding an external ?lter. At zero output current, the output may contain
low frequency components which exceed the ripple speci?cation. The output may be operated inde?nitely with
no load.
All models are fully operational and meet published speci?cations, including “cold start” at –40? C.
(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 Application Note.
(10) Regulation speci?cations describe the deviation as the line input voltage or output load current is varied from a
nominal midpoint value to either extreme.
(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 speci?cations when adjusting the output trim.
(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.
