Description

This reference design generates a regulated 12V output from a nominal 48V input. This design can handle up to 50A maximum current and 25A maximum current per phase. The LM5137F-Q1 controller provides switching signals to the LMG2100R026 half-bridge Gallium Nitride (GaN) field-effect transistor (FET) with an integrated gate driver.
