Basic
➀ Balanced "full-load" is 5V @ 3.3A/3.3V @ 5A. All models are specified with external
1µF ceramic output capacitors.
➁ See Technical Notes/Graphs for details.
➂ Devices may be ordered with On/Off Control function or a Sync function.
See Part Number Suffixes and Technical Notes for details.
➃ Applying a voltage to On/Off Control (pin 4) when no input power is applied to the
converter may 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 return pin (–Input).
➆ Demonstrated MTBF available on request.
