The TPS84320RUQ is an easy-to-use integrated power solution that combines a 3-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 design 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 up to 95% efficiency and excellent power dissipation with a thermal impedance of 13°C/W junction to ambient. The device delivers the full 3-A rated output current at 85°C ambient temperature without airflow.
The TPS84320 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs. Advanced packaging technology afford a robust and reliable power solution compatible with standard QFN mounting and testing techniques.
