Power Trends’ PT3101A (5V),
PT3102A (12V) and PT3103A (15V)
Isolated DC-DC Converters advance the
state-of-the-art for board-mounted con-
verters by employing high switching
frequencies greater than 650 KHz and
planar magnetics and surface-mount
construction. They feature the industry’s
smallest footprint, a power density of
15 Watts/in
3
, and operate at 80% effi-
ciency. They are designed for Telecom,
Industrial, Computer, Medical, and other
distributed power applications requiring
input-to-output isolation.
