Isolated 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 surface-mount construction. They feature the industry’s smallest footprint, a power density of 15 Watts/in3, and operate at 83% efficiency. They are designed for Telecom, Industrial, Computer, Medical, and other distributed power applications requiring input-tooutput isolation and an industrial temperature range.
