All models are specifi ed with external 0.47µF ceramic and 100µF tantalum output capacitors. ➁ See Technical Notes/Graphs for details. ➂ Applying a voltage to On/Off Control (pin 3) when no input power is applied to the converter can cause permanent damage. ➃ Output noise may be further reduced with the installation of additional external output capacitors. See Technical Notes. ➄ On/Off control is designed to be driven with open collector or by appropriate voltage levels. Voltages must be referenced to the –Input (Pin 2). ➅ Demonstrated MTBF available on request. ➆ For conditions with less than minimum loading, outputs remain stable. However, regulation performance will degrade. ➇ Input Ripple Current is tested/specifi ed over a 5-20MHz bandwidth with an external 22µF input capacitor and a simulated source impedance of 220µF and 12µH.
