Description

This document is an engineering report describing a 5 V / 3 A, 9 V / 3 A, 15 V / 3 A, 20 V 2.25 A USB PD PPS power supply. This power supply uses InnoSwitch3-Pro INN3368C-H301 IC and VP302 USB PD controller. This design shows the high power density and efficiency that is possible due to the high level of integration of the InnoSwitch3-Pro controller providing exceptional performance.
