For Thermal Shutdown
All models are specified with external 0.47μF ceramic output capacitors.
See Technical Notes/Graphs for details.
Applying a voltage to On/Off Control (pins 3 & 4) when no input power is applied to the
converter can cause permanent damage.
Output noise may be further reduced with the installation of additional external output
capacitors. See Technical Notes.
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).
Demonstrated MTBF available on request.
For conditions with less than minimum loading, outputs remain stable. However, regulation
performance will degrade.
Maximum applied voltage to On/Off pin (N suffix) less than 19.0V.
