Product Overview
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 provides
high power density with low noise and
high efficiency.
