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
