The headline number is the 2 A output from an 11-VQFN-HR package measuring 2x2 mm — that power density forces the PCB copper area to do the thermal work. ## Switching frequency: inductor sizing vs efficiency trade The switching frequency spans 1.5 MHz to 2.5 MHz. At the high end you shrink the inductor to 1 µH or 0.47 µH class, saving board area at the cost of slightly higher switching losses. At 1.5 MHz the efficiency peaks, but the inductor grows. The iDCS-Control scheme keeps the loop stable across that range without external compensation — one fewer BOM line to qualify. ## Input range and output — where it fits the rail budget The fixed 1.8 V output is a common core or I/O supply for MCUs, FPGAs, and sensors. TI lists the TPS6209718RWKR as Active.","metaTitle":"TI TPS6209718RWKR Buck Converter, 2 A, 1.5-2.5 MHz, 11-VQFN","metaDescription":"Texas Instruments TPS6209718RWKR step-down converter with iDCS-Control, 2.5-6 V input, fixed 1.8 V output at 2 A.
