Input voltage | 85-265 V |
Output 1 | 20 V / 3.25 A |
IC revision | A |
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.
