1 Introduction to Paralleling Current Sources

Both the TPS92520-Q1 and the TPS92519-Q1 are dual, synchronous buck LED drivers that can drive each channel as independent current sources. Connecting the device's channels together allows for the summation of each output current from the channels to a single channel, which means paralleling the drive currents. Paralleling the channels for each device is implemented differently. This application report will cover the different design considerations for the TPS92520-Q1 and the TPS92519-Q1.
