TI introduces smallest and most efficient SIMPLE SWITCHER® synchronous converters

07/06/2018

Texas Instruments (TI) introduced two wide-VIN synchronous SIMPLE SWITCHER® DC/DC buck regulators in ultra-small HotRod™ quad flat no-lead (QFN) packaging. The highly integrated 3-A LMR33630 and 2-A LMR33620 step-down voltage converters feature the industry's best full load efficiency – 92 percent – for rugged and reliable industrial power supplies with switching frequencies up to 2.1 MHz. Used in conjunction with TI's WEBENCH® Power Designer, the converters simplify power conversion and speed the design process.

The 3.8-V to 36-V LMR33630 and LMR33620 buck regulators are offered in 3-mm-by-2-mm thermally enhanced packaging. The small HotRod QFN package includes unique wettable flanks enabling post-solder optical inspection to simplify manufacturing and gives the LMR33630 the industry's highest 0.5A/mm2 power density at 3 A of current. Optimized package construction and symmetrical pin placement minimizes parasitic inductance and facilitate optimal placement of input bypass capacitors to mitigate conducted and radiated noise emissions.
