The Texas Instruments TPS650244RHBR is a highly integrated power management IC (PMIC) designed for applications powered by a single Li-ion or Li-Polymer cell. This device is targeted at providing core voltage, peripheral, I/O, and memory rails in processor-based systems.
Key features include three highly efficient step-down converters. The system voltage converter (VDCDC1) supports up to 1.6A, the memory voltage converter (VDCDC2) supports up to 1.6A, and the processor core converter (VDCDC3) supports up to 0.8A. The device also includes two 200mA general-purpose LDOs (LDO1 and LDO2) and a 30mA LDO for Vdd_alive.
The TPS650244RHBR operates over a temperature range of -40°C to 85°C. It is supplied in a 32-VQFN (5x5) package, suitable for surface mounting. The converters can enter a low power mode at light loads for maximum efficiency across a wide range of load currents.
This PMIC is ideal for applications such as cellular phones, smart phones, GPS devices, digital cameras, and PDAs that require multiple power rails from a single battery cell.
