All models are specified with external 0.47μF ceramic output capacitor.
See Technical Notes/Graphs for details.
Applying a voltage to On/Off Control (pin 4) when no input power is applied to the converter
can cause permanent damage.
Output noise may be further reduced with the addition of additional external output
capacitors. See Technical Notes. Use only as much output filtering as needed and no more.
Larger caps (especially low-ESR ceramic types) may slow transient response or degrade
dynamic performance.
The On/Off Control is designed to be driven with open-collector logic or the application
of appropriate voltage levels. Voltages may be referenced to the –Input (pin 2).
Demonstrated MTBF available on request.
