Basic
➀ All models are specified with no external output capacitors.
➁ See Technical Notes/Graphs for details.
➂ Devices may be ordered with On/Off Control function or a Sync function.
See Part Number Suffixes and Technical Notes for details.
➃ Applying a voltage to On/Off Control (pin 5) when no input power is applied to the
converter may cause permanent damage.
➄ Output noise may be further reduced with the installation of additional external output
capacitors.
➅ On/Off control is designed to be driven with open collector or by appropriate voltage
levels. Voltages must be referenced to the input return pin (–Input).
➆ Demonstrated MTBF available on request.
Absolute Maximum Ratings

88 Volts
Input Reverse-Polarity Protection
Current must be <3A. Brief duration
only. Fusing recommended.
Output Overvoltage Protection
+5V Outputs

Output Current
Current limited. Maximum current and
short-circuit duration are model
dependent.
Storage Temperature

These are stress ratings. Exposure of devices to any of these conditions may adversely
affect long-term reliability. Proper operation under conditions other than those listed in the
Performance/Functional Specifications Table is not implied, nor recommended.
