High-Current Trans-Inductors - PAL6374_HLT Series

 Pulse Electronics, a YAGEO Company, expands its inductor line with a trans-inductor-based voltage regulator developed in the common domain. The hybrid device mitigates ‎bandwidth limitations of existing VRM solutions and further drives performance improvements. The trans-inductor is similar to a ‎traditional one-turn VR inductor but has the addition of a second tightly coupled winding. The main low DCR primary is used in a ‎traditional VR inductor, having a PWM input with several phases feeding the output. Each single turn secondary is tied in a series loop ‎referenced to the local ground. When a load step occurs on a given phase, the resultant increase or decrease in the duty cycle is ‎reflected to its secondary winding; because the secondaries of each phase are in a series loop, this change can be seen immediately. ‎Through the magnetic coupling, this sensed change is reflected to each inductor’s primary winding. In effect, this allows all phases to ‎respond simultaneously to a load transient, greatly reducing the time needed for the converter to adjust. The PAL6374.xxxHLT series ‎is primarily used to power processors, memory, FPGAs, and ASICs in applications such as servers, datacenters, and storage systems‎.
