Description for the TPS84621

The TPS84621 is an easy-to-use integrated power solution that combines a 6-A DC-to-DCconverter with power MOSFETs, an inductor, and passives into a low profile, BQFN package. Thistotal power solution allows as few as three external components and eliminates the loopcompensation and magnetics part selection process.

The 9×15×2.8 mm BQFN package is easy to solder onto a printed circuit board and allows acompact point-of-load design with greater than 90% efficiency and excellent power dissipation witha thermal impedance of 13°C/W junction to ambient. The device delivers the full 6-A rated outputcurrent at 85°C ambient temperature without airflow.

The TPS84621 offers the flexibility and the feature-set of a discrete point-of-loaddesign and is ideal for powering performance DSPs and FPGAs. Advanced packaging technology afford arobust and reliable power solution compatible with standard QFN mounting and testingtechniques.
