Beschreibung

This document is an engineering report describing a 60 W USB PD 3.0 power supply using InnoSwitch3-Pro INN3379-H302 IC and VIA Labs VP302 USB PD controller. The USB PD source capabilities of the power supply are listed below.-PDO1: 5 V / 3 A (Fixed Supply)-PDO2: 9 V / 3 A (Fixed Supply)-PDO3: 15 V / 3 A (Fixed Supply)-PDO4: 20 V / 3 A (Fixed Supply)-PDO5: 3.3 V – 21 V / 3 A (Programmable Power Supply)This report demonstrates the high power density, exceptional performance, and high efficiency designs possible when the InnoSwitch3-Pro family of controllers is paired with the input capacitor volume-reduction capabilities of the MinE-CAP IC.The report contains the power supply specification, schematic diagram, printed circuit board layout, bill of materials, magnetics specifications, and performance data.
