Power Integrations INN4073C | Demoboard DER-928

Beschreibung

This document is an engineering report describing a 60 W USB PD power supply with 5 V / 3 A, 9 V / 3 A, 15 V / 3 A, 20 V / 3 A, output using InnoSwitch4-CZ INN4073C, ClampZero CZ1062M, and MinE-CAP MIN1072M. This design shows the high power density and efficiency that is possible due to the high level of integration of the InnoSwitch4-CZ active clamp controller providing exceptional performance and is paired with the input capacitor volume-reduction capabilities of the MinE-CAP IC.

Eigenschaften

• 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
• Meets DOE6 and CoC v5 2016 efficiency requirement
• Output overvoltage and overcurrent protection
• Integrated thermal protection
• <60 mW no-load input power, >20 mW consumed by micro controller
• Compact design with high power density: 30.3 W/ inch3 without enclosure (60 W / 1.77 in X 1.77 in X 0.63 in)

Typische Anwendungen

• High efficiency CV/CC power supplies
• High density flyback designs up to 110 W, High efficiency USB PD adapters.
