All models are specified with two external 0.47F multi-layer ceramic capacitors installed
across their output pins.
See Minimum Output Loading Requirements under Technical Notes.
See Technical Notes for details.
The On/Off Control and Trim functions are optional and must be installed by C&D.
See Optional Functions or contact C&D for details.
The On/Off Control is designed to be driven with open-collector logic or the application of
appropriate voltages (referenced to –Input, pin 2). Applying a voltage to the On/Off Control
pin when no input voltage is applied to the converter may cause permanent damage.
See Technical Notes.
Output noise maybe further reduced with the addition of additional external output
capacitors. See Technical Notes.
Operating temperature range without derating is model and input-voltage dependent.
See Temperature Derating.
