Texas Instruments TPS62177 | Demoboard TIDA-010047
22-W/in3, 93.1% peak efficiency, 100-W USB-PD 3.0 AC/DC adapter reference design with Si MOSFET
Overview
| Topology | Flyback Converter |
| Input voltage | 220-240 V |
| Output 1 | 5 V / 5 A |
| IC revision | E1 |
Description
This fully-tested reference design is a high-efficiency, high-power-density, AC/DC adapter solution with a wide input voltage range (100- to 240-V AC) for laptop adapters and smartphone charger applications. This design consists of a front-end transition-mode (TM) power factor correction (PFC) circuit based on the UCC28056 device, followed by an active-clamp flyback for isolated DC/DC conversion based on the UCC28780 device.
Features
- Relatively low-cost solution
- Solution based on the both-ended USB Type-C® cable
- Relatively high power density with active-clamp flyback topology
- Meets DoE level VI and CoC Tier2 regulations
- Robust protection built-in
Typical applications
- Notebook PC power adapter design
- Industrial AC/DC
- Mobile wall charger design / Other AC/DC adapters, PSU
