Operating input range from 4.2V to 60V. 2mm x 3mm HotRod™ QFN package. Junction temperature range from -40°C to 150°C. 26µA quiescent current. The list of amazing features is long. And that’s before you see the eye-popping efficiency plots. LMR36006/15 are the industrial buck converters you’ve been looking for.

Texas Instruments LMR360xx/LMR360xx-Q1 Step-Down Converters are an easy-to-use, synchronous, step-down DC/DC converter with integrated high-side and low-side power MOSFETs. These devices provide up to 0.6A (LMR36006/LMR36006-Q1) or 1.5A (LMR36015/LMR36015-Q1) of output current that is delivered over a wide input voltage range of 4.2V to 60V. Tolerance goes up to 66V. The LMR360xx/LMR360xx-Q1 uses peak-current-mode control to provide optimal efficiency and output voltage accuracy. Advanced high-speed circuitry allows the LMR360xx/LMR360xx-Q1 to regulate from an input of 20V to an output of 5V at a fixed frequency of 2.1MHz. Precision enable gives flexibility by enabling a direct connection to the wide input voltage or precise control over device start-up and shutdown. The power-good flag, with built-in filtering and delay, offers a true indication of system status eliminating the requirement for an external supervisor.
