➀ Balanced “full-load” is 5V @ 3.3A/3.3V @ 5A. All models are specified with external 1µF
➁ See Technical Notes/Graphs for details.
➂ Applying a voltage to On/Off Control (pin 4) when no input power is applied to the converter
➃ Output noise may be further reduced with the installation of additional external output capacitors.
➄ On/Off control is designed to be driven with open collector or by appropriate voltage levels.
