TPS84620 - 6 A Synchronous Buck, Integrated Power Solution

TIS TPS84620 iconThe 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 x 15 x 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.

The TPS84620 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs.
