40 Watt Hybrid
Proton Rad Hard 100K+® DC – DC Converters
 
Model 53629 is a high efficiency cross regulated quad output DC – DC converter
that incorporates a built-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 inputs are also provided.
Other input/output voltages 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.
