Power Integrations INN3266C-H210 | 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.

Features

• USB PD 3.0 with PPS support via single secondary-side IC (CCG3PA CYPD3175)
• InnoSwitch3-CP is the industry’s first AC/DC IC with isolated, safety rated integratedfeedback
• All the benefits of secondary-side control with the simplicity of primary-side regulation
  • Insensitive to transformer variation
• Built-in synchronous rectification for high efficiency
• Meets DOE6 and CoC V5 2016 efficiency requirement (>1 % efficiency margin)
• Micro stepping of voltages and CC thresholds in compliance with PPS protocol
• Output overvoltage and overcurrent protection
• <30 mW no-load input power
• Integrated thermal protection

Typical applications

• Charger / Adapter / USB-PD & Fast Chargers
