Texas Instruments recently launched a fully integrated power management solution for double date rate DDR2, DDR3, and DDR3L memory subsystems. Intended for use in automotive (e.g., infotainment and driver assistance systems) and industrial (e.g., measurement and automation) applications, the TPS54116-Q1 DC/DC buck converter is a 2.95-to 6-V input, 4-A synchronous step-down converter with a 1-A peak sink/source DDR termination and buffered reference.
Used with WEBENCH online design tools, the TPS54116-Q1 buck converter simplifies power conversion and speeds up the power-supply design process. It 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. Furthermore, it is synchronizable to an external clock.
The converter is packaged in a thermally enhanced 24-pin, 4 mm × 4 mm × 0.75 mm very thin quad flat no-lead (WQFN) package. It costs $2.50 in 1,000-unit quantities.
