Texas Instruments has introduced two wide-VIN synchronous SIMPLE SWITCHER DC/DC buck regulators in ultra-small HotRod quad flat no-lead (QFN) packaging. The highly integrated 3A LMR33630 and 2A LMR33620 step-down voltage converters feature full load efficiency - 92% - for rugged and reliable industrial power supplies with switching frequencies up to 2.1MHz. Used in conjunction with TI’s WEBENCH Power Designer, the converters simplify power conversion and speed the design process.
The 3.8-36V LMR33630 and LMR33620 buck regulators are offered in 3x2mm thermally enhanced packaging.
The small HotRod QFN package includes wettable flanks enabling post-solder optical inspection to simplify manufacturing and gives the LMR33630 the highest 0.5A/mm2 power density at 3A of current.
Optimised package construction and symmetrical pin placement minimises parasitic inductance and facilitate optimal placement of input bypass capacitors to mitigate conducted and radiated noise emissions. Watch the video, 'Reduce EMI and shrink solution size with HotRod packaging'.
