Block Diagram
EMI Filter (Optional)
Input filter components (C1, C2, L1) are used to help meet special
conducted emissions requirements for the PXF product. These
components should be mounted as close as possible to the DC-
DC converter; and all leads should be minimized to decrease
radiated noise.
Minimum Load
A 10% (of full load) minimum load is required to meet the
performance specifications. The unit does not maintain regulation
and operate properly under a no-load condition.
