TPS54116QRTWRQ1, Switching Voltage Regulators Automotive DDR Power Solution with 4-A, 2-MHz VDDQ DC/DC Converter, 1-A VTT LDO and VTTREF 24-

TPS54116-Q1 Synchronous Step-Down Converter Texas Instruments TPS54116-Q1 Synchronous Step-Down Converter comes with two integrated MOSFETs and 1A sink/source double data rate (DDR) VTT termination regulator with VTTREF buffered reference output. This buck regulator minimises solution size by integrating the MOSFETs and reducing inductor size with up to 2.5MHz switching frequency. The switching frequency can be set above the medium wave radio band for noise-sensitive applications and is synchronisable to an external clock. The synchronous rectification keeps the frequency fixed across the entire output load range. The efficiency is maximised through integrated 25mΩ low-side and 33mΩ high-side MOSFETs. The cycle-by-cycle peak current limit protects the device during an overcurrent condition. It is also adjustable with a resistor at the ILIM pin to optimise for smaller inductors.Learn more
