The TPS65056RSMT 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 step-down converters, capable of providing core and I/O voltages, alongside two 400-mA and two 200-mA LDO voltage regulators.
The step-down converters operate at a 2.25-MHz fixed frequency and can achieve up to 95% efficiency. They support an input voltage range from 2.5 V to 6 V and can deliver output currents of 1 A for DCDC1 and 0.6 A for DCDC2. These converters feature a power-save mode for light loads and can be forced into fixed-frequency PWM mode for low-noise applications. The output voltage accuracy in PWM mode is ±1%.
The integrated LDOs operate with an input voltage range of 1.5 V to 6.5 V, allowing them to be supplied from the step-down converters or directly from the battery. The device has a typical quiescent current of 32 μA for both DC-DC converters. The TPS65056RSMT is housed in a 32-VQFN (4x4) package and operates within an ambient temperature range of -40°C to 85°C.
