Successfully Boosting Power Densities & Raising Efficiency Levels

20 February 2024

In order to facilitate more effective power system implementations in space-constrained settings, while also keeping the associated expense down, Texas Instruments has just announced a pair of significant power conversion hardware offerings.

These are both being debuted at the Applied Power Electronics Conference (APEC) - which starts on the 25th February (and is being held in Long Beach, California). Firstly, there's the LMG2100R044 and LMG3100R017. Based on gallium-nitride GaN) technology, they are 100V-rated power stages that achieve power density figures surpassing 1.5kW/in3. Furthermore, the company claims these stages can half power losses compared to equivalent silicon (Si) arrangements (with 98% efficiency values being attained), as well as bringing down power system size for mid-voltage applications by at least 40%. Complementing them are the UCC33420-Q1 and UCC33420. Aimed at automotive and industrial usage, these 1.5W isolated DC/DC modules have 8x greater power density than equivalent discrete solutions, plus 3x greater power density than competing integrated solutions. They enable a 89% reduction in power system size and a substantial curbing in bill-of-materials (BoM) costs to be realised. 

“For power-supply designers, delivering more power in limited spaces will always be a critical design challenge,” states Kannan Soundarapandian, General Manager of High-Voltage Power at Texas Instruments. “Take data centres, for example - if engineers can design power-dense server power-supply solutions, data centres can operate more efficiently to meet growing processing needs while also minimizing their environmental footprint. We’re excited to continue to push the limits of power management by offering innovations that help engineers deliver the highest power density, efficiency and thermal performance.”
