Switching at 2.4 MHz lets the designer pick a small inductor — typically 0.47 µH to 1 µH — and keep the output ripple under 10 mV with ceramic output caps. The trade-off: the fast switching edge demands a tight power loop from input cap to inductor to output cap, with the switch node kept short to minimise radiated noise. ## Input range and output adjustability — fitting the rail The input range spans 2.4 V to 5.5 V, covering single-cell Li-Ion, 3.3 V, and 5 V buses. The output is adjustable from 0.8 V up to 5.5 V, set by a resistor divider on the FB pin. For a 1.8 V or 3.3 V rail, the feedback resistors are straightforward; for a sub-1 V core rail, the divider ratio pushes the upper resistor into the tens of kΩ range, which keeps the feedback node impedance manageable. The positive output configuration means the regulator sources current only — no sinking — so it's a straight step-down, not an inverting or SEPIC topology. ## Temperature grade and layout reality for the 9-VQFN A 2-layer board with a solid ground plane under the pad will keep the junction below 125°C at 6 A if the input-to-output differential is under 1.5 V; at higher differentials, a 4-layer board with thermal vias is the safer bet.

The actual achievable current depends on the input-to-output differential, ambient temperature, and the PCB's ability to sink heat from the 9-VQFN-HR thermal pad."},{"question":"What is the switching frequency of TPS62867RQYR?","answer":"The switching frequency is 2.4 MHz. This high frequency allows the use of small inductors (0.47 µH to 1 µH typical) and ceramic output capacitors, keeping the total solution footprint compact. The trade-off is that the fast switching edges require a careful layout to keep the power loop tight and minimise EMI."},{"question":"What package does TPS62867RQYR come in?","answer":"The TPS62867RQYR is supplied in a 9-VQFN-HR package with dimensions 1.5 mm x 2.5 mm.
