3 Description

The TPS84210RKG is an easy-to-use integrated

power solution that combines a 2-A DC/DC converter

with power MOSFETs, an inductor, and passives into

a low profile, BQFN package. This total power

solution requires as few as 3 external components

and eliminates the loop compensation and magnetics

part selection process.

The 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

12°C/W junction to ambient. The device delivers the

full 2-A rated output current at 85°C ambient

temperature without airflow.

The TPS84210 offers the flexibility and the featureset

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.
