40-V Boost Converter with Integrated 1.2-A Switch from TI

Texas Instruments has introduced a tiny, high-voltage boost converter with an integrated 40-V, 1.2-A FET and a wide input-voltage range of 3-V to 18-V. The high-efficiency device supports boost, SEPIC (single-ended primary inductor converter) and flyback topologies, which are used to regulate single or dual Li-Ion battery inputs. Available in a 2 mm x 2 mm QFN package, the converter simplifies design in industrial or medical point-of-load applications, such as 5-V to 12-V or 12-V to 24-V systems.
