Description and Introduction

CONSTANT CURRENT LED DRIVER WITH DIGITAL AND PWM BRIGHTNESS CONTROL The TPS61061DRBRG4 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 28V (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:** VSON-8 (DRB)  

### **Descriptions:**  
- The TPS61061DRBRG4 is a high-efficiency, low-quiescent-current boost converter with a fixed-frequency PWM controller.  
- It is designed for battery-powered applications requiring a regulated output voltage higher than the input supply.  
- Features include internal soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 1.8V to 6V input.  
- **High Output Voltage:** Adjustable up to 28V.  
- **Integrated Power Switch:** 1.2A switch current limit.  
- **Fixed-Frequency Operation:** 1.2MHz for reduced noise and smaller external components.  
- **Low Quiescent Current:** 19µA (typical) for improved efficiency in light-load conditions.  
- **Protection Features:** Overcurrent protection, thermal shutdown, and undervoltage lockout (UVLO).  
- **Small Package:** VSON-8 (3mm x 3mm) for space-constrained applications.  

This device is commonly used in portable electronics, LED drivers, and battery-powered systems requiring high-voltage conversion.
