15 WATT 48V TO 5V/12V/15V
ISOLATED DC-DC CONVERTER
Revised 8/13/98
• Power Density 15 Watts/in3
• Wide Input Voltage Range
36V to 75V
• 80% Efficiency
• 500 VDC Isolation
• Industry’s Smallest Footprint
• Fast Transient Response
• No External Components Required
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/in3, and operate at 80% effi-
ciency. They are designed for Telecom,
Industrial, Computer, Medical, and other
distributed power applications requiring
input-to-output isolation.
