48-V / 25-A negative-to-positive synchronous buck-boost reference design for power amplifiers

This reference design is a negative-to-positive synchronous buck-boost converter for power amplifier applications. The circuit is powered from the nominal -48-V system source to provide an output voltage of +48 V at 25 A. The design uses two dual synchronous boost controllers for 4-phase operation (...)
