TIDA-01622 Reference Design

Texas Instruments

30-W/in3: 92% Efficiency: 65-W USB Type-C PD AC/DC Adapter Reference Design

Description

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.

Features
  • High efficiency (92% 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*26.8mm*20mm)
