➀ All models are specified with two external 0.47µF multi-layer ceramic capacitors installed
across their output pins.
➁ See Minimum Output Loading Requirements under Technical Notes.
➂ See Technical Notes for details.
➃ The On/Off Control, Sync and Trim functions are optional and must be installed by DATEL.
See Optional Functions or contact DATEL for details.
➄ 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.
➅ Output noise maybe further reduced with the addition of additional external output
capacitors. See Technical Notes.
➆ Operating temperature range without derating is model and input-voltage dependent.
See Temperature Derating.
