4A Synchronous DC/DC, Design Simplification and System Size Miniaturization for Automotive and Industrial Applications

TI announced that it is launching the industry's first fully integrated power management solution for DDR (double data rate) 2, DDR3, and DDR3L memory subsystems for automotive and industrial applications.

The new TPS54116-Q1 DC/DC buck converter is a 4A synchronous step-down converter with a 2.95V to 6V input. It integrates 1A peak sink/source DDR termination and a buffered reference, allowing for a reduction in system size by up to 50% compared to a discrete implementation.

The TPS54116-Q1 is designed for automotive applications such as infotainment, ADAS, and instrument panels, but it can also be used for DDR memory in communications, test and measurement equipment, and factory automation equipment.

In addition, using TI’s WEBENCH® online design tool, power converter design using the TPS54116-Q1 can be done easily and conveniently, and power supply design can be done more quickly.

The TPS54116-Q1 buck converter is a new addition to TI's industry-leading DC/DC converter product portfolio that provides a switching frequency of up to 2.5 MHz and minimizes solution size by incorporating MOSFETs and reducing inductor size. In addition, since the switching frequency can be set above the medium-wave radio band, it is suitable for use in noise-sensitive applications and can be synchronized with an external clock.

When using TI’s TDA3 system-on-chip, an automotive power reference design for low-power TDA3x-based systems can be used to design an integrated and optimizedly sized power supply for ADAS with TPS54116-Q1 functionality.
