Adapter Power Solutions

Adapter power products from TI provide reliable, efficient, low-cost power solutions for a wide range of AC/DC charger and adapter applications. Innovative, high-efficiency power management controllers reduce both energy consumption and solution size. Universal charge controllers help designers minimize environmental impact and reduce charging times with standards compliance. With or without wires, TI solutions provide best-in-class no load power performance and highest average system efficiency.

LM5023 - AC-DC Quasi-Resonant Current Mode PWM Controller



Key features and benefits of the UCC28710:

  • No cable compensation required
  • Skip cycle mode reduces power consumption at light loads for energy conservation applications(ENERGY STAR, CEPCP, etc.)
  • Quasi-resonant mode reduces switching losses and improves active efficiency
  • Reduces EMI
  • Hiccup mode prevents over-heating during extended overload conditions

UCC28710 No-Load Adapter Power



The UCC28710 family of flyback power supply controllers have a 700-V start-up switch that achieves less than 10 mW of no-load standby power in 5- and 10-W smartphone and tablet adapters.

Key features and benefits of the UCC28710:

  • Primary Side Regulation eliminates the opto-coupler feedback circuit and associated components to reduce component count and increase power supply reliability
  • <10 mW no-load power performance exceeds the 5-star EC IPP rating for no-load stand-by power requirements
  • No cable compensation required
  • Skip cycle mode reduces power consumption at light loads for energy conservation applications(ENERGY STAR, CEPCP, etc.)

UCC28700 No-Load Adapter Power



The highly efficient UCC28700 flyback controller achieves low standby power rating with the smallest solution size and component count resulting in the greatest power density.

Key features and benefits of the UCC28700:

  • Lowest standby power <30-mW standby consumption, only 1.5-μA startup current
  • Highest integration with primary side regulation eliminates need for opto-couplers and additional external circuitry
