Abstract

The TPS92633-Q1 is a linear three-channel constant-current LED driver designed for high brightness LEDs in automotive rear light applications. As requirements continue to evolve in the rear light market, LED drivers are expected to achieve greater flexibility and more comprehensive functionality. This application note provides some design guidelines on how to use TPS92633-Q1 device to achieve a higher output current by paralleling output channels and make sure normal operation while maintaining diagnostic functions.
