The TPS62590DRVR is a 1 A synchronous step-down (buck) converter from Texas Instruments, switching at 2.25 MHz.
The adjustable output goes from 0.75 V up to the input voltage, so it can power 1.2 V, 1.8 V, or 3.3 V loads from the same BOM by changing one feedback resistor. Output is positive and adjustable; the 0.75 V minimum suits the latest low-voltage cores in MCUs, FPGAs, and RF transceivers.
