### **Descriptions:**  
The TPS65050RSMRG4 is a highly integrated PMIC designed for applications requiring multiple power rails, such as processors and FPGAs. It includes three step-down DC-DC converters (buck regulators) and two low-dropout (LDO) regulators, providing efficient power management in a compact form factor.  

### **Features:**  
- **Integrated Power Solution:** Combines buck converters and LDOs in a single chip.  
- **Dynamic Voltage Scaling (DVS):** Supports adjustable output voltages via I²C interface.  
- **Power Sequencing:** Configurable startup and shutdown sequencing.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Protection Features:** Overcurrent, overvoltage, and thermal shutdown protection.  
- **I²C Interface:** Allows digital control and monitoring.  

This device is commonly used in portable electronics, embedded systems, and industrial applications.

Application Scenarios & Design Considerations

6-CHANNEL POWER MGMT IC WITH TWO STEP-DOWN CONVERTERS AND 4 LOW-INPUT VOLTAGE LDOs

Alternative Part Number

  • TPS65053RSMR --: Same TPS6505x power-management family in the same QFN package with comparable multi-rail regulators, making it a close functional substitute.
  • MAX8660ETL+ --: Integrated multi-output PMIC for portable processors with similar rail count and I2C control, suitable as a cross-vendor alternative.
  • DA9063 --: Configurable multi-rail PMIC with comparable regulator count and sequencing features, usable as a higher-integration alternative.
  • TPS65052RSMR --: Sister device in the TPS6505x series with similar integrated power rails and identical package footprint, suitable for drop-in evaluation.
