Buck-boost controller lifts efficiency & cuts EMI

TI’s LM5175 flexible DC/DC controller addresses a wide variety of buck, boost, and buck-boost applications from output power of a few watts to greater than 100W using a single device. A proprietary switching scheme maximises efficiency in the buck-boost transition region and uses a single inductor to further reduce board space. The LM5175’s robust gate drive (2A at 7.5 V) enables wide V_IN MOSFETs to switch faster and more efficiently. Optional hiccup mode short-circuit protection prevents thermal runaway during extended load current faults, reducing thermal stress by up to 30%.

Together with TI's award-winning WEBENCH online design tools, the LM5175 offers engineers the opportunity to get their industrial and automotive applications to market faster.

WEBENCH Designer and Power Architect enable end-to-end circuit design, simulation and optimisation for footprint, price and efficiency, with the ability to download schematic and PCB layout files directly into CAD tools. Component libraries include more than 40,000 components from 120 manufacturers, and TI’s distribution partners update price and availability hourly. Offered in eight languages, users can compare complete system designs and make supply-chain decisions in minutes.

The LM5175 is priced at $4.25 in 1,000-unit quantities, and can be sampled through Electronic Specifier's Sample Centre programme, by clicking here.
