While power demands increase, board area and height are becoming limiting factors. Power designer must squeeze more circuitry into their applications to differentiate their products, while increasing efficiency and enhancing thermal performance. TI continues investing in advanced technology and develops solutions enabling designers to attain best-in-class power density. Higher power levels in smaller form-factors are now achievable using TI’s advanced circuit-design, process, and packaging technology.
