3 DESCRIPTION

The TPS84620RUQ is an easy-to-use integrated

power solution that combines a 6-A DC/DC converter

with power MOSFETs, an inductor, and passives into

a low profile, BQFN package. This total power

solution allows as few as 3 external components and

eliminates the loop compensation and magnetics part

selection process.

The 9×15×2.8 mm BQFN package is easy to solder

onto a printed circuit board and allows a compact

point-of-load design with greater than 90% efficiency

and excellent power dissipation with a thermal

impedance of 13°C/W junction to ambient. The

device delivers the full 6-A rated output current at

85°C ambient temperature without airflow
