Balanced "full-load" is 5V @ 1.5A/3.3V @ 2.25A. All models are specied with external
0.47F ceramic and 100F tantalum output capacitors.
See Technical Notes/Graphs for details.
Applying a voltage to On/Off Control (pin 3) when no input power is applied to the
converter can 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 (Pin 2).
Demonstrated MTBF available on request.
For conditions with less than minimum loading, outputs remain stable. However, regulation
performance will degrade.
Input Ripple Current is tested/specied over a 5-20MHz bandwidth with an external 22F
input capacitor and a simulated source impedance of 220F and 12H. See I/O Filtering,
Input Ripple Current and Output Noise for details.
