Product Summary

The TPS650061RUKR is a single chip Power Management IC for portable applications. It combines a single step-down converter with two low dropout regulators. The step-down converter enters a low power mode at light load for maximum efficiency across the widest possible range of load currents. For low noise applications, the TPS650061RUKR can be forced into fixed frequency PWM via a pin. The applications of the TPS650061RUKR are (1)Point of Load; (2)Embedded Processor Power; (3)Cell Phones, Smart-Phones; (4)PDAs, Pocket PCs; (5)Portable Media Players.
