Primary to Secondary Insulation Level Functional
? All models are speci?ed with no external I/O capacitors.
? See Technical Notes/Graphs for details.
? Applying a voltage to the On/Off Control (pin 3) when no input power is applied to the
converter can cause permanent damage to the converter.
? Output noise may be further reduced with the addition of additional external output capacitors.
See Technical Notes.
? The On/Off Control is designed to be driven with open-coolector logic or the application of
appropriate voltage levels. Voltages may be referenced to the –Input (pin 2).
? Input Ripple Current is tested/speci?ed over a 5-20MHz bandwidth with an external 33μF
input capacitor and a simulated source impedance of 220μF and 12μH. See I/O Filtering, Input
Ripple Current and Output Noise for details.
