Description and Introduction

High Brightness White LED Driver in 2mm x 2mm QFN Package 6-SOT-23 -40 to 85 The TPS61165DBVR is a boost converter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable up to 18V  
- **Output Current:** Up to 1.2A (switch current limit)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS61165DBVR is a high-efficiency, synchronous step-up DC-DC converter designed for small, low-power applications. It integrates a low-resistance power switch to minimize power loss and improve efficiency. The device is suitable for battery-powered systems, portable electronics, and LED drivers.  

### **Features:**  
- **Integrated Synchronous Rectifier:** Improves efficiency by reducing diode losses.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Low Quiescent Current:** 30µA (typical) for improved battery life.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Thermal Shutdown Protection:** Safeguards the device from overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This information is based on TI's official datasheet for the TPS61165DBVR.
