Integrated DDR memory claims an industry first
Claimed to be the industry’s first integrated power management solution for double date rate (DDR)2, DDR3 and DDR3L memory sub-systems in automotive and industrial applications, the TPS54116-Q1 DC/DC buck converter are announced by Texas Instruments. The 2.95 to 6.0V input, 4A synchronous step-down converter has a 1.0A peak sink/source DDR termination. Buffered reference is claimed to reduce system size by up to 50 per cent compared to discrete implementations.
Designed for automotive applications such as infotainment, ADAS and instrument clusters, the memory can also power DDR memory in telecommunications, test and measurement, and factory automation equipment.
It can be used in conjunction with the company’s WEBENCH online design tools.
The buck converter provides up to 2.5MHz switching frequency and minimises size by integrating the MOSFETs. Switching frequency can be set above the medium-wave radio band for noise-sensitive applications and is synchronisable to an external clock.
It is AEC-Q100-qualified with 4kV electrostatic discharge (ESD) protection.
Available in volume, the converter is packaged in a thermally enhanced 24-pin, 4.0 x 4.0 x 0.75mm thin quad flat no-lead package.
