48V 15 WATT ISOLATED

DC-DC CONVERTER

Power Trends’ PT4100 series of Isolated

• -40°C to +85°C Operating

Temperature Range

• 1500 VDC Isolation

• Power Density 15 Watts/in³

• Wide Input Voltage Range

36V to 75V

• 82% Efficiency

• Small Footprint

• Fast Transient Response

• UL Approved

48V 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 sur-

face-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.
