48V
Application Notes Mechanical Outline Product Selector Guide
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 Power Trends' PT3101A (5V), PT3102A (12V) and PT3103A (15V)
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 80% efficiency. They are designed for T lecom, e Industrial, Computer, Medical, and other distributed power applications requiring input-to-output isolation.
