Power Integrations INN3366C-H301 | Demoboard DER-613

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 Weltrend WT6635P 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 using highly optimized, low pin count USB PD Controller WT6635P
• 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
