This reference design is for automotive tail-light applications. The design features TPS92638-Q1 linear LED driver powered by a synchronous buck converter (LM53601-Q1) that is directly supplied from the automotive-battery voltage. This design helps pass CISPR 25 Class 5 conduct emission and radiated emission without an CMCC filter. The reference design also optimizes efficiency.
