### **Descriptions:**  
The TPS61161ADRVR is a high-efficiency, step-up DC-DC converter designed for driving white LEDs or providing a regulated voltage. It integrates a 1.2A switch and supports adjustable output voltage via an external resistor divider.  

### **Features:**  
- **High Efficiency:** Up to 90% with integrated synchronous rectification.  
- **Adjustable Output:** Configurable via external feedback resistors.  
- **PWM Dimming Control:** Supports brightness adjustment for LED applications.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Small Footprint:** Compact 6-pin WSON package for space-constrained designs.
