Product details

14mOhm Rds(on) — conduction loss floor for the BOM

The TPS22921YFPR is a single-channel, high-side load switch from Texas Instruments, built around a P-channel MOSFET with a typical on-resistance of 14mOhm. That number sets the conduction loss at any load current: at 2A the resistive drop is 28 mV, which keeps the voltage headroom tight for the downstream regulator or load. The switch operates from 0.9V to 3.6V on the load side, covering single-cell Li-Ion through 3.3V logic rails without needing a separate bias supply.

6-DSBGA package — footprint and assembly reality

The TPS22921YFPR is supplied in a 6-bump DSBGA package, designated 6-DSBGA.

Frequently asked questions

What is the Rds(on) of TPS22921YFPR?

Typical on-resistance is 14mOhm. This is the conduction loss figure used for thermal and efficiency calculations at the rated 2A continuous output.

Is TPS22921YFPR RoHS compliant?

Yes, it is ROHS3 compliant.
