Product Overview
Shown actual size:
2.28 x 2.2 x 0.5 in
57,9 x 55,9 x 12,7 mm
These DC-DC converter modules use
advanced power processing, control and
packaging technologies to provide the
performance, flexibility, reliability and
cost effectiveness of a mature power
component. High frequency ZCS/ZVS
switching provide high power density
with low noise and high efficiency.
