Description

This document is an engineering report describing a 3.3 V – 21 V / 5 A PPS output USB Type-C and USB PD charger using the HiperPFS-4 PFS7628C PFC controller, InnoSwitch3Pro flyback controller and VIA Labs VP302 USB Type-C USB PD controller. This design shows the high power density and efficiency that is possible due to the high level of integration of the HiperPFS-4 and InnoSwitch3-Pro controllers.

Features

  • InnoSwitch3-Pro is industry first AC/DC IC with isolated, safety rated integrated feedback controller
  • 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 Tier 2 V5 2016
  • <50 mW no-load input power at 230 VAC
  • Primary sensed overvoltage protection
  • Very high power density using GaN switch
  • 14.5 W / inch3 without enclosure
  • Very low component count
  • EMI filter and PFC stage – 44 components
  • Flyback stage - 52 components
  • USB PD controller stage - 14 components
  • Very high average efficiency
  • 3.3 V Output – 89.33% at 115 VAC and 87.14% at 230 VAC
  • 5 V Output – 91.53% at 115 VAC and 91.49% at 230 VAC
  • 9 V Output – 91.96% at 115 VAC and 92.59% at 230 VAC
  • 15 V Output – 90.80% at 115 VAC and 90.48% at 230 VAC
  • 20 V Output – 91.09% at 115 VAC and 91.17% at 230 VAC

Typical applications

  • Mobile Phone/Tablet/Laptop Adapter
