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 9×11×2.8 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 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 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.
