Power Integrations INN3266C | Demoboard DER-603

Description

This document is an engineering report describing a 27 W USB PD power supply which can be configured for 5 V / 3.0 A, 9 V / 3 A or 3-11V with adjustable voltage and current to comply with USB PD 3.0 and PPS protocol. This power supply uses the InnoSwitch3-CP integrated power supply controller from Power Integrations and Cypress CCG3PA (CYPD3175) 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-CP controller providing exceptional performance. This document contains the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout, and performance data

Features
