The TPS65014 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 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 through the serial interface. Each LDO operates with an input voltage range of 1.8 V to 6.5 V, thus allowing them to be supplied from one of the step-down converters or directly from the battery.
