6 Summary

48 VIN applications larger VIN and load current range puts a bigger focus on line and load regulation for the pre-regulator in those designs. LM5013-Q1, a popular 48 VIN pre-regulator uses a COT topology, which by nature, is controlled by feedback voltage variation. Increasing line and load ranges do not create worry by following the steps outlined in this article to minimize the output variation. The concepts covered in this article need to be used in your future design to make sure best practices are being followed and the highest performance can be achieved.
