DESCRIPTION
FES single output DC/DC converters provide up to 300 watts of output power and up to 60 amperes of output current
in a full-brick package. The FES converters feature open-frame packaging, along with planar magnetics and a high
efficiency topology, to provide maximum useable power density. The FES converters use 100% surface-mount
construction and are fully compatible with production board washing processes.
