Packaged in a 3623 ChiP package, the devices deliver up to 240 W of power and up to 653 W/in.3 (39.8 W/cm3) power density in a topology of high-frequency zero-voltage switching (ZVS). Their efficiency is up to 93 percent of the input voltage.

Applications for commuter and freight rail systems include:

· Electric door openers

· Engine control

· Motor drive controllers

· Braking systems

· Lighting

· Ticketing machines
