The Texas Instruments TPS650242RHBT is an integrated power management IC suitable for applications powered by a single Li-Ion or Li-Polymer cell. It features three highly efficient step-down converters and three low-dropout regulators (LDOs) to provide multiple power rails for processor-based systems.
The device includes a 1.6-A step-down converter for system voltage (VDCDC1), a 0.8-A step-down converter for memory voltage (VDCDC2), and another 0.8-A step-down converter for the processor core (VDCDC3). The core voltage (VDCDC3) offers selectable outputs of 1.0 V or 1.5 V. Additionally, it provides a 30-mA LDO for Vdd_alive and two 200-mA general-purpose LDOs (LDO1 and LDO2).
Designed for efficiency across a wide load current range, the converters enter a low-power mode at light loads. The TPS650242RHBT operates with an input voltage range of 2.5 V to 6 V and has an operating temperature range of -40°C to 85°C. It is supplied in a 32-VQFN (5x5 mm) package suitable for surface mounting.
Key electrical characteristics include a typical switching frequency of 2250 kHz and a quiescent current of 0.135 mA. The IC also incorporates fault protection for over-temperature and under-voltage conditions.
