Power Integrations INN4177C-H189 | Demoboard DER-930

Description

This engineering report describes a 180 W, 20 V / 9 A output power supply using HiperPFS-5 PFS5177F, InnoSwitch4-CZ INN4177C-H189, and ClampZero CPZ1076M.This design shows the high power density and efficiency that is possible due to the highlevel of integration of the InnoSwitch4-CZ active clamp flyback controller providingexceptional performance.

Features

• Integrated PFC and flyback stages for a very low component count design
• Quasi-resonant DCM control ensures low switching losses, small inductor size, and permits use of low-cost boost diode
• InnoSwitch4-CZ – active clamp flyback switcher IC with integrated high-voltage PowiGaN, synchronousrectification 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
• 93.7% Full-load efficiency at 115 VAC
• 92.8% Full-load efficiency at 90 VAC, meets DOE6 and CoC v5 2016 efficiency requirement
• Output overvoltage and overcurrent protection
• Integrated thermal protection
• <100 mW no-load input power at 230 VAC
• Meets CISPR22 / EN55022 Class B conducted EMI
