Description

This reference design uses four LMG708B0-Q1 synchronous buck controllers configured as four-phase, interleaved, synchronous buck converters. The converter generates a regulated 5V output from a nominal 48V input and can handle up to 80A max current at 20A per phase. The LMG708B0-Q1 provides integrated switching with Gallium Nitride (GaN) field-effect transistors (FETs).
