Recently, Texas Instruments has introduced TPS54116-Q1 DC/DC buck converter. Apparently, it is industry’s first fully integrated management solution for double date rate (DDR)2, DDR3 and DDR3L memory subsystems in automotive and industrial applications. It’s a 4-A synchronous step-down converter with 2.95-V to 6-V input along with a 1-A peak sink/source DDR termination and buffered reference. It is capable of decreasing the system size by up to 50% as compared to the discrete implementations.
TPS54116-Q1 has been specifically designed to be utilised in automotive applications like instrument clusters, infotainment, and advanced driver assistance systems. However, it can also be used to power DDR memory in fields like factory automation equipment, telecommunication as well as test and measurement. It is used alongside TI’s WEBENCH online design tools for the purpose of power conversion and speeding up the power supply design process.
Apart from the above-mentioned functions, this newly added tool in the DC/DC portfolio of TI encloses a lot more features. It renders a switching frequency of up to 2.5 MHz, which can be set above the medium-wave radio band for noise-sensitive applications. Also, the frequency can be synchronised to an external clock. Further, it integrates the MOSFETs and reduces inductor’s size, thereby minimizing the solution size.
Texas Instrument’s TPS54116-Q1 carries the following advantageous features:
• It’s Automotive Electronics Council (AEC)-Q100 qualified along with 4-kV electrostatic discharge (ESD) protection.
• It has got current mode control and external clock synchronization which allows the frequency to remain fixed across the whole output load range.
• It’s integrated with low and high power MOSFETs and 1-A sink/source DDR VTT termination support 4A of continuous output current.
