Description and Introduction

CONSTANT CURRENT LED DRIVER The TPS61043DRB is a boost converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 0.9V to 5.5V  
- **Output Voltage Range:** Adjustable up to 5.5V  
- **Output Current:** Up to 300mA (dependent on input/output conditions)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SON-6 (DRB)  

### **Descriptions:**
- The TPS61043DRB is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications.  
- It integrates a synchronous rectifier to improve efficiency and reduce external component count.  
- The device is optimized for low-input voltage operation, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**
- **Low Start-up Voltage:** As low as 0.9V  
- **Synchronous Rectification:** Improves efficiency and reduces power loss  
- **Adjustable Output Voltage:** Via external resistor divider  
- **Low Quiescent Current:** 19µA (typical)  
- **Integrated Soft-Start:** Prevents inrush current  
- **Thermal Shutdown Protection:** Safeguards against overheating  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions  

This information is based solely on the manufacturer's datasheet and technical documentation.
