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