The TPS84210RKG is an easy-to-use integrated power solution that combines a 2-A DC/DCconverter with power MOSFETs, an inductor, and passives into a low profile, BQFN package. Thistotal power solution requires as few as 3 external components and eliminates the loop compensationand magnetics part selection process.

The BQFN package is easy to solder onto a printed circuit board and allows a compactpoint-of-load design with greater than 90% efficiency and excellent power dissipation with athermal impedance of 12°C/W junction to ambient. The device delivers the full 2-A rated outputcurrent at 85°C ambient temperature without airflow.

The TPS84210 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.
