The Texas Instruments TPS650240RHBR is an integrated power management IC (PMIC) designed for applications powered by a single Li-Ion or Li-Polymer cell. It provides three highly efficient step-down converters and two general-purpose LDOs to supply core voltage, peripheral, I/O, and memory rails.
Key electrical specifications include a 1.6-A step-down converter for system voltage (VDCDC1) with up to 97% efficiency, a 1.6-A step-down converter for memory voltage (VDCDC2) with up to 95% efficiency, and a 0.8-A step-down converter for the processor core (VDCDC3) with 90% efficiency. It also features a 30-mA LDO for Vdd_alive and two 200-mA LDOs for general-purpose use. The device operates at a 2.25-MHz switching frequency and has a low quiescent current of 85 μA.
Designed for split-supply DSP and microprocessor solutions, this PMIC is suitable for cellular phones, smart phones, GPS devices, and digital cameras. The TPS650240RHBR is housed in a 32-VQFN package and supports surface mount installation. It operates within an ambient temperature range of -40°C to 85°C.
