The TPS57112C-Q1 device is a full-featured 6-V, 2-A, synchronous step-down current-mode converter with two integrated MOSFETs.

The TPS57112C-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 TPS57112C-Q1 device provides accurate regulation for a variety of loads with a ±1% voltage reference (Vref) over temperature.

The integrated 12-mΩ MOSFETs and 515-µA typical supply current maximize efficiency. Using the enable pin to enter the shutdown mode reduces supply current to 5.5 µA, typical.

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 when the output is within 93% to 107% of its nominal voltage.

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