Abstract
A power converter including a power train, a controller and a driver. The power train includes a switch that conducts for a duty cycle and provides a regulated output characteristic for the power converter, and a micromagnetic device interposed between the switch and the output of the power converter. The micromagnetic device includes a substrate, and a magnetic core layer formed over the substrate from a magnetic alloy including iron, cobalt and phosphorous. A content of the cobalt is in a range of 1.8 to 4.5 atomic percent. A content of the phosphorus is in a range of 20.1 to 30 atomic percent. A content of the iron is substantially a remaining proportion of the magnetic alloy. The controller provides a signal to control the duty cycle of the switch. The driver provides a drive signal to the switch as a function of the signal from the controller.
