Texas Instruments LMR360xx/LMR360xx-Q1 Step-Down Converters
Texas Instruments LMR360xx/LMR360xx-Q1 Step-Down Converters are easy-to-use, synchronous, step-down DC/DC converters 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) output current 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 for 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. With built-in filtering and delay, the power-good flag accurately indicates system status, eliminating the requirement for an external supervisor.
The LMR360xx/LMR360xx-Q1 is in a HotRod™ package, enabling low EMI, higher efficiency, and a small package-to-die ratio. The device requires few external components and has a pinout designed for a simple PCB layout. The small solution size and feature set of the LMR360xx/LMR360xx-Q1 is designed to simplify implementation for a wide range of end equipment. The Texas Instruments LMR360xx-Q1 devices are AEC-Q100 qualified for automotive applications.
