Introducing industry's first fully integrated DDR memory power solution
TI's 4-A synchronous DC/DC buck converter simplifies design and shrinks system size in automotive and industrial applications
Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's first fully integrated power management solution for double date rate (DDR)2, DDR3 and DDR3L memory subsystems in automotive and industrial applications. The TPS54116-Q1 DC/DC buck converter is a 2.95-V to 6-V input, 4-A synchronous step-down converter with a 1-A peak sink/source DDR termination and buffered reference that reduces system size by up to 50 percent compared to discrete implementations.
The TPS54116-Q1 DC/DC buck converter from Texas Instruments is a 2.95-V to 6-V input, 4-A synchronous step-down converter with a 1-A peak sink/source DDR termination and buffered reference that reduces system size by up to 50 percent compared to discrete implementations.
Designed for automotive applications such as infotainment, advanced driver assistance systems (ADAS) and instrument clusters, the TPS54116-Q1 can also power DDR memory in telecommunication, test and measurement, and factory automation equipment. Used in conjunction with TI's WEBENCH® online design tools, the TPS54116-Q1 simplifies power conversion and speeds the power-supply design process. For more information, samples and an evaluation module, see www.ti.com/tps54116q1-pr.
The newest addition to TI's industry-leading DC/DC converter portfolio, the TPS54116-Q1 buck converter provides up to 2.5-MHz switching frequency and minimizes solution size by integrating the MOSFETs and reducing inductor size. The switching frequency can be set above the medium-wave radio band for noise-sensitive applications and is synchronizable to an external clock. Read the blog post, "Four design tips to obtain 2-MHz switching frequency."

TPS54116-Q1 key features and benefits
Integrated low- and high-side power MOSFETs and a 1-A sink/source DDR VTT termination regulator support 4 A of continuous output current.
Current-mode control with external clock-synchronization capability keeps the frequency fixed across the entire output load range.
Automotive Electronics Council (AEC)-Q100 qualified with 4-kV electrostatic discharge (ESD) protection for automotive applications.
