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.
