Power Integrations INN3366C - H301 | Demoboard DER-701

Description

This document is an engineering report describing a 27 W USB PD power supply with 5 V / 3 A, 9 V / 3 A, or 3.3 V – 11 V Programmable Power Supply (PPS) output using InnoSwitch3-Pro INN3366C-H301 IC and VIA Labs 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 (8 pin)
  • Sophisticated telemetry and comprehensive protection features
• USB PD 3.0 with PPS using 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 (20 mV) and CC thresholds (50 mA) in compliance with PPSprotocol
• Output overvoltage and overcurrent protection
• Integrated thermal protection
• <30 mW no-load input power

Typical applications

• Mobile Phone Charger
