Block Diagram
EMI Filter (Optional)
Input filter components (C1, C2, L1) are used to help meet special
conducted emissions requirements for the PXD 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
The PXD20 does not require a minimum load for proper
operation.
A 10% (of full load) minimum load is required on PXD10 and
PXD15 models to meet the performance specifications. These
models do not maintain regulation and operate properly under a
no-load condition.
