TI: wide-VIN DC/DC buck regulators simplify the design of industrial power supplies

Texas Instruments introduced two wide-VIN synchronous SIMPLE SWITCHER DC/DC buck regulators in ultra-small HotRod 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.

The new DC/DC converters provide an operating input voltage range as high as 36 V for nominal 12-V or 24-V systems such as factory and home automation, motor drives, inverters and servo control units. For applications up to 60 V, TI offers the 600-mA LMR36006 and 1.5-A LMR36015 synchronous step-down converters in pin-compatible packages.

The 36-V regulators feature full load efficiency of 92 percent at 24 VIN, 5 VOUT and a 400-kHz switching frequency. Very low 24-µA typical standby quiescent current increases light load efficiency.

In addition to the QFN package, the 36-V regulators are also available in a thermally efficient, 8-pin, 5x-6-mm SOIC package that delivers an ultra-low thermal coefficient of 13.8ºC/W (ΨJB) to further improve reliability.
