TPS65023RSBT

The Texas Instruments TPS65023RSBT is an integrated Power Management IC (PMIC) suitable for applications powered by a single Li-Ion or Li-Polymer cell. It provides three highly efficient step-down converters for core, system, and memory voltage rails, along with a 30 mA LDO/Switch for the real-time clock and two 200 mA general-purpose LDOs.

Key electrical specifications include a maximum output current of 1.7 A for the processor core converter, up to 1.2 A for the system voltage converter, and 1.0 A for the memory voltage converter. The device operates with an input voltage range of 2.5 V to 6 V and offers output voltages as low as 0.6 V. It features a low quiescent current of 85 µA and a shutdown current of 23 µA.

The TPS65023RSBT supports dynamic voltage management for the processor core and allows for preselectable LDO voltages via digital input pins. Communication is handled through an I2C-compatible serial interface. The device is housed in a 40-WQFN (5x5 mm) package and operates within a temperature range of -40°C to 85°C.

This PMIC is designed for processor-based systems requiring multiple power rails and dynamic power savings. Its integrated features simplify power management design in devices such as digital media players, smartphones, and digital still cameras.
