Description
Selection Chart
The 25-30 Watt Triple Series opens up new application areas
in high efficiency DC/DC conversion. The unique dual control
loop output design allows for independent regulation of both
the single and dual outputs. This increases the total output
accuracy by up to 10:1 over competitive designs. The design
also eliminates cross regulation from the +5 section to the
dual outputs. The 25-30 Watt Triple Series runs at 80-85%
efficiency.
