4 Reference Shared Boost System

This section provides a reference design for a shared boost application. The performance curves included in Section 3 were tested on this reference evaluation platform.

This reference platform is powered from a >45W USB-C adapter. The TPS25730 resistors for ADCINx can be adjusted for different power setups.
