48V
PT4100 Series
Power Trends’ PT4100 series of Isolated
48V DC-DC Converters advance the state-ofthe-art for board-mounted converters 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/in3, and operate at 82% efficiency.
They are designed for Telecom, Industrial,
Computer, Medical, and other distributed
power applications requiring input-to-output
isolation and an industrial temperature range.
