USA: Pulse Electronics Corp. announced its new EP13 Plus platform that delivers 25 percent 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 (9-57v and 33-57v) and can provide six different output voltage combinations from 3.3v to 24v. 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 percent more power throughput and lower winding resistance.
Pulse Electronics’ EP13 Plus series transformers are designed for either active clamp forward (PA3856.XXXNL) or continuous mode flyback (PA3855.XXXNL) topologies and offer 24 different output voltage and power combinations.
The transformers come in an industry standard package of 14.0(h)x17.7(l) mm. The EP13 Plus series is used in a wide variety of electronic applications including wireless base stations, IP phones, security cameras, automation and test equipment, and networking gear.
