Description

This engineering report describes a 60 W 20 V 3 A output power supply using InnoSwitch4-CZ INN4075C-H180 and ClampZero CPZ1075M. This design shows the high power densityand efficiency that is possible due to the high level of integration of the InnoSwitch4-CZactive clamp flyback controller providing exceptional performance

Features

  • InnoSwitch4-CZ – active clamp flyback switcher IC with integrated high-voltage PowiGaN, synchronous rectification and FluxLinkTM feedback
  • Zero voltage switching in both CCM and DCM operating conditions
  • All the benefits of secondary-side control with the simplicity of primary-side regulation
  • Insensitive to transformer variation
  • 95% full-load efficiency at 230 VAC

  • 94.5% full-load efficiency at 115 VAC

  • 93.9% full-load efficiency at 90 VAC, meets DOE6 and CoC v5 2016 efficiency requirement
  • High power density: 28.45 W/in3
  • Output overvoltage and overcurrent protection
  • Integrated thermal protection
  • <60 mW no-load input power at 230 VAC
  • Meets CISPR22 / EN55022 Class B conducted EMI
