Bias Supply

The motherboard requires one 12-V bias supply. A linear dropout regulator (in LMG34XX-BB-EVM) or buck regulator (in LMG342X-BB-EVM) steps the voltage down to a tightly regulated 5-V for the logic and auxiliary power of the LMG342XR0X0 when the LMG342XEVM-04X is configured in isolated power mode.
