Additional Notes

Model 53629 is a high efficiency cross regulated quad output DC-DC converter that incorporates a bu8idl in Mil-STD-461 EMI filter

High efficiency and excellent cross regulation are achieved by using a planar power transformer and GaAs rectifiers. Sync and Enable input are also provided.

Other input/output voltages are available on special order

A combined total of 40W may be drawn on all 4 outputs. Up to 750mA is available from the auxiliary outputs provided the total output power does not exceed 40W.
