➀ All models are specified with external 0.47µF ceramic output capacitors.
➁ See Technical Notes/Graphs for details.
➂ The On/Off Control function can be replaced with a Sync function. See Part Number
Suffixes and Technical Notes for details.
➃ Applying a voltage to On/Off Control (pins 3 & 4) when no input power is applied to the
converter can cause permanent damage.
➄ Output noise may be further reduced with the installation of additional external output
capacitors. See Technical Notes.
➅ On/Off control is designed to be driven with open collector or by appropriate voltage
levels. Voltages must be referenced to the –Input (pin 2).
➆ Demonstrated MTBF available on request.
➇ For conditions with less than minimum loading, outputs remain stable. However, regulation
performance will degrade.
➈ Maximum applied voltage to On/Off pin (N suffix) less than 19.0V.
