Higher voltage batteries are becoming more prevalent in automotive and eBike applications. The extended VIN range is causing designers to examine more closely the line regulation of the pre-regulator. Furthermore, the pre-regulator might need to support a no load to full load condition, so load regulation is also of high importance. This application note reviews line and load regulation for 48-V battery and eBike, pre-regulators using LM5013-Q1 as an example.
