The 2.4 MHz switching frequency keeps the inductor small — 1 µH to 2.2 µH range — which matters when board area is tight.
Input range and output flexibility
The output is adjustable from 1.2 V up to 5.5 V, set by a resistor divider.

Frequently asked questions
What is the maximum output current of TPS63020DSJR?
The internal switch is rated for 3.5 A. The actual output current the regulator can deliver depends on the input-to-output voltage ratio and the inductor chosen.
Is TPS63020DSJR pin compatible with the base TPS63020?
Yes — the DSJR suffix indicates the reel/tape packaging variant; the silicon and pinout are identical to the base TPS63020 in the same 14-VSON package.
