### **Descriptions:**  
The TPS65146RGER is a compact, high-efficiency power management IC designed to generate both positive and negative supply voltages from a single input. It integrates a synchronous boost converter for the positive output and an inverting converter for the negative output, making it suitable for applications requiring dual-rail power supplies.  

### **Features:**  
- **Dual Output Generation:** Provides both positive and negative regulated voltages.  
- **High Efficiency:** Up to 90% efficiency with synchronous rectification.  
- **Low Quiescent Current:** 20 µA (typical) in shutdown mode.  
- **Adjustable Output Voltages:** Positive and negative outputs can be independently set.  
- **Integrated Power Switches:** Reduces external component count.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent and Thermal Protection:** Enhances system reliability.  
- **Small Footprint:** 24-pin VQFN package (4x4 mm) for space-constrained designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
