The TPS6507x family of devices are single-chip power management ICs (PMICs) for portable applications consisting of a battery charger with power path management for a single Li-Ion or Li-Polymer cell. The charger can either be supplied by a USB port on pin USB or by a DC voltage from a wall adapter connected to pin AC. Three highly efficient 2.25-MHz step-down converters are targeted at providing the core voltage, memory, and I/O voltage in a processor-based system. The step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents.
