Texas Instruments Addresses Critical Power-Management Design Challenges For EVs And Industrial Systems Directly

Written by Stephen Vicinanza

Texas Instruments is addressing some of the more pressing power management issues facing designers to improve reliability and sustainability going forward.

The company is showcasing some of its newest additions to its power-management portfolio and offering system-level solutions for increasing power density.

TI is launching three new products to help engineers mitigate EMI and noise in their systems

The 36V, 3-A – LMQ66430, and LMQ66430-Q1 buck converters.

  • Integrate two input bypass capacitors and one boot capacitor. This allows engineers to easily meet the requirements for CISPR 25 class 5 EMI standards and also offers the best-in-class total solution size. The additional benefits of 1.5 – µA quiescent current (Iǫ)as well as a reduced bill-of-materials cost.
  • The article outlining how to best utilize buck converters to lower EMI and save board space can be found at the link to the TI website

The TPS7A94 low-dropout linear regulator

  • The TPS7A94 low-dropout (LDO) linear regulator combines a low noise of 0.46 µV(RMS) – a 42% better rate than other solutions – with high-power-supply rejection ratio. This gives designers more room to improve system accuracy and precision in those applications that call for high sensitivity to noise, such as medical devices, wireless infrastructure, and radar.
  • The technical article on the LDO basics comes in parts Part 1 is out now: LDO Basics: noise – Part 1.

Some of the advantages and benefits that can help engineers defeat critical power-management design issues, that TI has seen are

  • Increasing power density. – An 800-V 11-kW three-level, three-phase, gallium nitride (GaN)-based active neutral-point clamped inverter power stage
  • Lowering EMI – This is for the automotive and industrial sectors and improves filter size. The buck converters above help are used for lowering EMI.
  • Enabling safer systems. High voltage isolation technologies that provide reliability. The UCC5870-Q1 isolated gate driver and the UCC14240-Q1 isolated DC/DC bias supply module, both provide system efficiency with 30A of peak current and maintain reliability through isolation, protection, and diagnostics.

At events such as this past APEC, the experts at TI have been demonstrating advances and innovation in a variety of power-related sectors. Always with an eye toward helping the automotive and industrial fields reach new potentials and collaborate on a broad range of power management initiatives.
