UL Approved
Power Trends鈥?PT4100 series of Isolated
48V DC-DC Converters advance the state-of-
the-art for board-mounted converters by
employing high switching frequencies greater
than 650 KHz and planar magnetics and sur-
face-mount construction. They feature the
industry鈥檚 smallest footprint, a power density of
15 Watts/in
3
, and operate at 82% efficiency.
They are designed for T
elecom, Industrial,
Computer, Medical, and other distributed
power applications requiring input-to-output
isolation and an industrial temperature range.
