The TPS62160DGKT is a Texas Instruments DCS-Control™ synchronous step-down converter that switches at 2.25 MHz. The 1 A continuous output covers point-of-load rails like 3.3 V or 1.8 V from a 5 V or 12 V intermediate bus.
Input range and output adjust — fitting the rail budget
Input range runs from 3 V minimum to 17 V maximum, so it handles a 5 V regulated rail, a 12 V unregulated bus, or a 3-cell Li-ion stack without a pre-regulator.
The 8-VSSOP package (3.00 mm × 3.00 mm body, 0.65 mm pitch) is a standard footprint that routes easily on a 2-layer PCB with a solid ground plane under the exposed thermal pad.
