1.4.2 Adjustable UVLO

The undervoltage lockout (UVLO) can be adjusted externally using R1 (REN(TOP)) and R2 (REN(BOT)). R1 and R2 are not populated on the EVM, which uses the internal UVLO default settings. See the TPS568215 datasheet (SLVSDI8) for detailed instructions for setting the external UVLO.
