TPS65011 Description
The TPS65011 device is an integrated power and battery management IC for applications powered by one Li-Ion or Li-Polymer cell and which require multiple power rails. The TPS65011 provides two highly efficient, 1.25-MHz step-down converters targeted at providing the core voltage and peripheral, I/O rails in a processor-based system. Both stepdown converters enter a low-power mode at light load for maximum efficiency...
