 Complete Integrated Power Solution Allows Small Footprint Low-Profile Design "  The TPS84620RUQ is an easy-to-use integrated power solution that combines a 6-A DC/DC converter with power MOSFETs, an inductor, and passives into a low profile, BQFN package. This total power solution allows as few as 3 external components and eliminates the loop compensation and magnetics part selection process. 
  Efficiencies Up To 96% "
 Wide-Output Voltage Adjust 1.2 V to 5.5 V with 1% Reference Accuracy " Optional Split Power Rail allows input voltage down to 1.7 V "
 Adjustable Switching Frequency (480 kHz to 780 kHz) " Synchronizes to an External Clock " Adjustable Slow-Start " The 9×15×2.8 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 13°C/W junction to ambient. The 
 Output Voltage Sequencing / Tracking " Power Good Output " device delivers the full 6-A rated output current at 85°C ambient temperature without airflow. 
 Programmable Undervoltage Lockout (UVLO) " Output Overcurrent Protection " Over Temperature Protection " The TPS84620 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 
 Pre-bias Output Start-up " Operating Temperature Range: –40°C to 85°C " power solution compatible with standard QFN mounting and testing techniques.
