Style 1 EVMs support the LMG3650R0## devices where the pin 7 is connected to GND. Style 2 EVMs are able to support LMG3651R0##, LMG3656R0##, LMG3657R0## devices where pin 7 is configured for LDO5V, Zero-voltage detection (ZVD), or Zero-current detection (ZCD). The Rdson values will be interchangeable for each style EVM.
