Description for the TPS54116-Q1

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.

Using the enable pins to enter a shutdown mode reduces supply current to 1-µA. Under voltage lockout thresholds can be set with a resistor network on either enable pin. The VTT and VTTREF outputs are discharged when disabled with ENLDO.

Full integration minimizes the IC footprint with a small 4 mm × 4 mm thermally enhanced WQFN package.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
