Beschreibung
This fully tested, USB power delivery reference design is a high efficiency, high power density, AC/DC adapter solution with a wide input voltage range (85 - 265VAC) for laptop adapters and smartphone charger applications. It adopts active-clamp-flyback topology controlled by TI’s newest ACF controller UCC28780 as the mainly power supply stage. This design uses TPS25740B, TI’s PD source controller, to achieve a full PD 2.0 function. The design achieves a peak efficiency of 92% at a very high switching frequency. The design’s power density is increased to 30 W/in3, which is much higher than traditional solutions.
Eigenschaften
- High Efficiency (92% Peak Value)
- High Power Density (30 W/in³)
- Low Power Consumption at No Load (60 mW)
- Low Input Power at Light Load (0.5 W) at 20-VOUT,0.25-W Output
- Fully Compatible With USB PD 2.0 Standard With 5-V/3-A, 9-V/3-A, 15-V/3-A, 20-V/3.25-A Output
- Active-Clamp Flyback + SR Topology
- Small Size (62 mm × 26.8 mm × 20 mm)
Typische Anwendungen
- Consumer AC/DC / Industrial AC/DC
