description
The Interpoint® SMRT Series™ of dc-dc converters offers up
to 35 watts of power in a radiation tolerant design. The low
profile SMRT converters are manufactured in our fully certified
and qualified MIL-PRF-38534 production facility and packaged
in hermetically sealed steel cases. They are ideal for use in
programs requiring high reliability, small size, and high levels of
radiation hardness assurance.
The SMRT converters are switching regulators which use a
two-phase, phase shifted flyback design with a nominal switching
frequency of 300 kHz. Close regulation is maintained with
advanced constant frequency pulse width modulation design
techniques. The SMRT’s feed-forward compensation and
discontinuous topologies provide high levels of input-to-output
ripple rejection. See Figure 10 on page 29, Figure 29 and
Figure 30 on page 33 and Figure 45 and Figure 46 on page
36.
Two independent feedback loops are used to regulate the dual
and triple outputs, one feedback loop regulates the two-phased
single output. Each set of outputs is electrically isolated from the
other and from the input. This product configuration eliminates
cross regulation effects between output sets.
Configurations:
• Single Output: One dual-phase output
• Dual Output: Two isolated single-phase outputs
• Triple Output: One single-phased output (Main) isolated
from one single-phase dual output (± Auxiliary)
