5.4.7 TPS92682EVM-069 + TPS92520EVM-133 + TPS92662EVM6-901 Connection and Power UP

Another example is using TPS92682EVM-069, TPS92520EVM-133, and the TPS92662EVM6-901. The TPS92682EVM-069 and the TPS92520EVM-133 can be connected together such that the TPS92682EVM-069 boost a lower input voltage, such a battery, and boost it to a higher voltage for use by the buck LED driver (TPS02520EVM-133). The TPS92662EVM6-901 is a lighting matrix manager that has the ability to individually perform shunt FET dimming of the LEDs in the string. The LEDMCUEVM-132 and the GUI support these features by using the SPI bus and the UART over CAN hardware of the LEDMCUEVM-132. Here is a typical setup for controlling and testing the "TPS92520, TPS92682, TPS92662 - LPP074 - E2" selection from EVM Selection and Setup screen.
