TPS65014 锂电池供电系统的电源和电池管理 IC
TPS65014 描述
The TPS65014 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 TPS65014 provides two highly efficient, step-down converters targeted at providing the core voltage and peripheral, I/O rails in a processor based system. Both step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents. The LOW_PWR pin allows the core converter to lower its output voltage when the application processor goes into deep sleep. The TPS65014 also integrates two 200-mA LDO voltage regulators, which are enabled via the serial interface. Each LDO operates with an input voltage range between 1.
