15 WATT 24V TO 5V/12V/15V

ISOLATED DC-DC CONVERTER

Revised 5/15/98

• Power Density 15 Watts/in³

• Wide Input Voltage Range

18V to 40V

• 81% Efficiency

• 500 VDC Isolation

• Small Footprint

Isolated DC-DC Converters advance the

state-of-the-art for board-mounted convert-

ers by employing high switching frequencies

greater than 650 KHz and planar magnetics

and surface-mount construction. They fea-

ture the industry’s smallest footprint, a power

density of 15 Watts/in³, and operate

• No External Components Required

at 80% efficiency. They are designed for

Telecom, Industrial, Computer, Medical,

and other distributed power applications

requiring input-to-output isolation.
