Description and Introduction

White LED Driver with Digital and PWM Brightness Control in 2mm x 2mm WSON Package 6-WSON -40 to 85 The TPS61161DRVR is a boost converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Up to 18V (adjustable)  
- **Output Current:** Up to 1.2A (switch current limit)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin WSON (DRV)  

### **Descriptions:**  
The TPS61161DRVR is a high-efficiency, synchronous boost converter designed for applications requiring a regulated output voltage higher than the input supply. It integrates a low-resistance power switch and synchronous rectifier to improve efficiency.  

### **Features:**  
- **Integrated Synchronous Rectifier:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 28µA (typical) in shutdown mode.  
- **Soft-Start Function:** Prevents inrush current.  
- **Overcurrent and Thermal Protection:** Enhances reliability.  
- **Small Footprint:** Suitable for space-constrained designs.  

This device is commonly used in portable electronics, LCD displays, and battery-powered applications.
