TPS84621 - 6-A Synchronous Buck / Integrated Power Solution

General Description

The TPS84621 is an easy-to-use integrated power solution that combines a 6-A DC-to-DC converter with power MOSFETs, an inductor, and passives into a low profile, BQFN package.

This total power solution allows as few as three 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.
