Description

The TPS84621RUQT is an easy-to-use synchronous buck Integrated Power Solution that combines a 6A DC-to-DC converter with power MOSFETs, an inductor and passives into a low profile. This total power solution allows as few as 3 external components and eliminates the loop compensation and magnetic part selection process. It 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 thermal impedance of 13°C/W junction to ambient. The device delivers the full 6A rated output current at 85°C ambient temperature without airflow. It offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs.
Complete integrated power solution allows small footprint, low-profile design
