Description and Introduction

White LED Driver with Digital and PWM Brightness Control in 2mm x 2mm WSON Package 6-WSON -40 to 85 The TPS61161DRVT is a boost converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 6V  
- **Output Voltage Range:** Up to 18V (adjustable)  
- **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:** 6-pin WSON (DRV)  

### **Description:**  
The TPS61161DRVT is a high-efficiency, synchronous step-up DC-DC converter designed for applications requiring high output voltage from low input voltage sources. It integrates a power switch and synchronous rectifier to minimize external components and improve efficiency.  

### **Features:**  
- **Integrated 1.2A Switch:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 28µA (typical) for improved light-load efficiency.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Synchronous Rectification:** Enhances efficiency compared to diode-based solutions.  
- **Small Footprint:** 6-pin WSON package (2mm x 2mm) for space-constrained designs.  

This device is commonly used in battery-powered applications, OLED displays, and portable electronics requiring high-voltage generation from low-voltage sources.
