The TPS62140ARGTR: The 2.5 MHz switching frequency supports a small inductor and ceramic output capacitor, keeping the solution footprint compact.
The output is adjustable from 0.9 V up to 6 V, covering the low-voltage supply needs of modern FPGAs, MCUs, and SoC cores without an intermediate LDO. The synchronous rectifier (integrated high-side and low-side FETs) eliminates the external Schottky diode, improving efficiency and reducing BOM count.
The TPS62140ARGTR is pin-compatible with the TPS62140 base part number — the 'RGT' suffix denotes the 16-VQFN package and the 'R' suffix indicates Tape & Reel packaging. Within the TPS6214x family, the 1 A TPS62130 and 2 A TPS62140 share the same pinout and package, differing only in output current rating.
At 2 A output and high ambient temperatures near 85°C, the exposed pad of the 16-VQFN package must be soldered to a sufficient copper area on the PCB with thermal vias to dissipate heat. A separate heatsink is not required if the PCB layout follows the datasheet thermal guidelines.
