The EVM provides two current-limit settings. If a different setting is required, then populate header J2 with
a shorting jumper and modify resistor R3 using the current limit resistor calculator, TI Literature Number
SLVC163 .
See the TPS2552/3 data sheet for the worst-case current-limit variation.
