This reference design is a power supply generating a regulated 12V output from a nominal 48V battery input (ranging from 30V to 60V). The circuit is designed for 20A continuous output current. The LM5148-Q1 buck controller provides switching signals to a LMG2100R044 half-bridge GaN power stage with integrated gate driver.
