Description for the TPS65023

The TPS65023x device is an integrated power management IC for applications powered by one
Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65023x provides threehighly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O, andmemory rails in a processor-based system. The core converter allows for on-the-fly voltage changesthrough serial interface, allowing the system to implement dynamic power savings. All threestep-down converters enter a low-power mode at light load for maximum efficiency across the widestpossible range of load currents.

The TPS65023x also integrates two general-purpose 200-mA LDO voltage regulators, which areenabled with an external input pin. Each LDO operates with an input voltage range from 1.5 V to 6.5V, thus allowing them to be supplied from one of the step-down converters or directly from thebattery. The default output voltage of the LDOs can be digitally set to 4 different voltagecombinations using the DEFLDO1 and DEFLDO2 pins. The serial interface can be used for dynamicvoltage scaling, masking interrupts, or for disabling or enabling and setting the LDO outputvoltages. The interface is compatible with both the fast and standard modeI2C specifications, allowing transfers at up to 400 kHz. TheTPS65023x isavailable in a 40-pin WQFN package, and operates over a free-airtemperature of –40°C to 85°C.
