Power Trends鈥?PT4104A (5V), PT4105A (12V)
and PT4106A (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 sur-
face-mount construction. They feature the industry鈥檚
smallest footprint, a power density of 15 Watts/in
3
, and
operate at 83% 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.
