Fully-integrated DC/DC Power Solution

Texas Instruments recently expanded the Thunderbolt portfolio with the TPS65980 DC/DC switching regulator, the first fully integrated power solution for bus-powered Thunderbolt applications. The regulator is the centerpiece of the Thunderbolt single port peripheral reference design, simplifying the power chain and speeding the design of bus-powered applications, such as hard drives, solid state drives and audio and video solutions. 

In addition to the regulator, the company offers a full line of power management, switches, multiplexers and interface solutions for Thunderbolt applications. For hosts and peripherals, the TPS22981 power mux, TPS22920L load switch and the LM3481 boost converter facilitate the delivery and receipt of power to both the active cable and the connected device. The HD3SS0001video switch connects directly to the Thunderbolt controller switching the Thunderbolt UART transmit/receive pair and DisplayPort Main Link. In cable solutions, the TPS22986 power mulitplexer automatically selects the proper 3.3-V supply to provide power to the active cable circuitry.
