Description
General part information
TPS54116-Q1 Series
The TPS54116-Q1 device is a full featured 6-V, 4-A, synchronous step down converter with two integrated MOSFETs and 1-A sink/source double data rate (DDR) VTT termination regulator with VTTREF buffered reference output.
The TPS54116-Q1 buck regulator minimizes solution size by integrating the MOSFETs and reducing inductor size with up to 2.5-MHz switching frequency. The switching frequency can be set above the medium wave radio band for noise sensitive applications and is synchronizable to an external clock. Synchronous rectification keeps the frequency fixed across the entire output load range. Efficiency is maximized through integrated 25-mΩ low-side and 33-mΩ high-side MOSFETs. Cycle-by-cycle peak current limit protects the device during an overcurrent condition and is adjustable with a resistor at the ILIM pin to optimize for smaller inductors.
The VTT termination regulator maintains fast transient response with only 2 × 10-µF ceramic output capacitance reducing external component count. The TPS54116-Q1 uses remote sensing of VTT for best regulation.
