The TPS65054RSMT from Texas Instruments is an integrated power-management IC designed for applications requiring multiple power rails, typically powered by a single Li-Ion or Li-Polymer cell. This device integrates two highly efficient, 2.25-MHz step-down converters capable of providing core and I/O voltages for processor-based systems. These converters feature a power-save mode for light loads to maximize efficiency across a wide range of currents.
The TPS65054RSMT also includes two general-purpose 400-mA LDOs and two 200-mA LDOs, each operating with an input voltage range from 1.5 V to 6.5 V. These LDOs can be supplied from the step-down converters or directly from the main battery. The device supports digital voltage selection for both DC-DC converters and LDOs, offering design flexibility.
With an input voltage range of 2.5 V to 6 V for the DC-DC converters and 1.5 V to 6.5 V for the LDOs, the TPS65054RSMT is suitable for various portable applications. It operates within a temperature range of -40°C to 85°C and comes in a 32-VQFN (4x4) package with a surface mount type. The device achieves up to 95% efficiency and has a typical quiescent current of 32 μA for both DC-DC converters.
