The TPS57114C-Q1 device is a full-featured 6-V, 4-A, synchronous step-down current-mode converter with two integrated MOSFETs.

The TPS57114C-Q1 device enables small designs by integrating the MOSFETs, implementing current-mode control to reduce external component count, reducing inductor size by enabling up to 2-MHz switching frequency, and minimizing the IC footprint with a small 3-mm × 3-mm thermally enhanced QFN package.

The TPS57114C-Q1 device provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (V_ref) over temperature.

Efficiency is maximized through the integrated 12-mΩ MOSFETs and 515-µA typical supply current. Using the enable pin, shutdown supply current is reduced to 5.5 µA by entering a shutdown mode.

The internal undervoltage lockout setting is 2.45 V, but programming the threshold with a resistor network on the enable pin can increase the setting. The slow-start pin controls the output-voltage start-up ramp. An open-drain power-good signal indicates the output is within 93% to 107% of the nominal voltage.

Frequency foldback and thermal shutdown protect the device during an overcurrent condition.
