Texas Instruments  LMZ31503RUQT

The LMZ31503 power module is an easy-to-use integrated power solution that combines a 3-ADC/DC converter with power MOSFETs, a shielded inductor, and passives into a low profile, QFNpackage. This total power solution allows as few as 3 external components and eliminates the loopcompensation and magnetics design process.

The 9×15×2.8 mm QFN package is easy to solder onto a printed circuit board and allows acompact point-of-load design with up to 95% efficiency and excellent power dissipation with athermal impedance of 13°C/W junction to ambient. The device delivers the full 3-A rated outputcurrent at 85°C ambient temperature without airflow.

The LMZ31503 offers the flexibility and the feature-set of a discrete point-of-loaddesign and is ideal for powering performance DSPs and FPGAs. Advanced packaging technology afford arobust and reliable power solution compatible with standard QFN mounting and testingtechniques.
