3A rail in a 1.5 mm² footprint
The TPS6283810YFPR: The 3.5 MHz switching frequency lets you use a small inductor and output capacitor, which is the main reason to pick this part over a slower regulator — the total solution fits in roughly 1.5 mm² of board area with the 6-bump DSBGA package. Output is adjustable from 0.6 V up to 4 V, and the synchronous rectifier means no external Schottky diode is needed. The single output is positive-configuration.
125°C junction — under-hood and industrial ambient
The base product number is TPS6283810. The YFPR suffix denotes the 6-DSBGA package and tape-and-reel shipping medium.
