PA3855/PA3856 Series EP13 Plus DC/DC SMT Transformers

Pulse Electronics’ DC/DC transformer platform provides >25% more power handling capability

Image of Pulse Electronics Corporation's PA3855/PA3856 Series EP13 Plus DC/DC SMT TransformersPulse Electronics Corporation announces the EP13 Plus platform which delivers 25% more power handling capability than the industry-standard EP13 platform in the same PCB footprint. This catalog series of 12 isolation transformers is designed for multiple input voltage ranges (9-57 V and 33-57 V) and can provide six different output voltage combinations from 3.3 V to 24 V. The transformers are used in DC/DC power supplies for Power-over-Ethernet (PoE, PoE+), datacom, telecom, and industrial applications.

Pulse’s EP13 Plus platform incorporates two innovative features that advance the wire-wound transformer technology. The first innovation is the use of a modified core with an increased cross-sectional area to reduce the number of turns necessary for a given output voltage, or to increase the output power by better utilization of the available winding window. The second innovation is a new bobbin lead shape which allows for an increased number of lead wire terminations. This helps avoid damaging the leads or causing solder bridges to adjacent leads during IR reflow. Optimization of the magnetic core combined with the modified lead design of the winding termination give the EP13 Plus 25% more power throughput and lower winding resistance.
