TPS650231 Overview
The TPS650231 device is an integrated power management IC for applications powered by one Li-Ion or Li-Polymer cell, and which requires multiple power rails. The TPS650231 provides three highly efficient step-down converters targeted at providing the core voltage, peripheral, I/O, and memory rails in a processor-based system. The core converter allows for on-the-fly voltage changes through serial interface, allowing...
