Power Integrations INN3368C-H301 | Demoboard DER-704

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.

Features

• InnoSwitch3-Pro - digitally controllable CV/CC QR flyback switcher IC with integrated highvoltageMOSFET, synchronous rectification and FluxLinkTM feedback
  • I2C interface enables low pin count USB PD controller (10 pin)
  • Sophisticated telemetry and comprehensive protection features
• USB PD 3.0 with PPS highly optimized low pin count USB PD controller VP302
• All the benefits of secondary-side control with the simplicity of primary-side regulation
  • Insensitive to transformer variation
• 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
• 20 mV voltage step / 50 mA current step in PPS mode

Typical applications

• Mobile Phone Charger
