描述
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 94% at a very high switching frequency. The design’s power density is increased to 30 W/in3, which is much higher than traditional solutions.
特性
- High efficiency (94% peak value)
- High power density (30W/in³)
- Low no load power consumption (60mW)
- Low light load input power (0.5W), @20Vout/0.25W output
- Fully compatible with USB PD 2.0 standard, with 5V/3A, 9V/3A, 15V/3A, 20V/3.25A output
- Active-clamp flyback + SR topology
- Small size (62mm*28.6mm*18.4mm)
