资 源 简 介
The TPS65021 is an integrated Power Management IC for applicaTIons powered by one Li-Ion or Li-Polymer cell, and which require mulTIple power rails. The TPS65021 provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O and memory rails in a processor based system. All three step-down converters enter a low-power mode at light load for maximum efficiency across the widest possible range of load currents. The TPS65021 also integrates two general-purpose 200 mA LDO voltage regulators, which are enabled with an external input pin. Each LDO operates with an input voltage range between 1.5 V and 6.5 V, allowing them to be supplied from one of the step-down converters or directly from the battery.
