Description

This power-supply reference design supports VCCIN_AUX rail in Intel® Alder Lake and Raptor Lake platform. Using TPS51215A controller combined with an operational amplifier could support the control functions including VID control, load line (LL) and current monitor (IMON). The position for test tool interposer is reserved in this reference design to help with evaluation.
