The TPS84A20 is an easy-to-use integrated power solution that combines a 10-A DC/DCconverter with power MOSFETs, an inductor, and passives into a low profile, QFN package. This totalpower solution allows as few as three external components and eliminates the loop compensation andmagnetics part selection process.

The 10-mm × 10-mm × 4.3-mm QFN package is easy to solder onto a printed circuit board andallows a compact point-of-load design. Achieves greater than 95% efficiency and excellent powerdissipation capability with a thermal impedance of 13.3°C/W. The TPS84A20 offers the flexibilityand the feature-set of a discrete point-of-load design and is ideal for powering a wide range ofICs and systems. Advanced packaging technology affords a robust and reliable power solutioncompatible with standard QFN mounting and testing techniques.
