Abstract

This application note summarizes a typical schematic and layout design for 24-channel LED driver, TPS929240-Q1, to achieve high BCI (Bulk Current Injection) immunity performance with test set-up and result analysis. The test is based on TPS929240-Q1 evaluation board, which passes international standard ISO11452-4 test level IV (200mA).
