- **Efficiency:** Up to 95%  
- **Quiescent Current:** 19 µA (typical)  
- **Shutdown Current:** < 1 µA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TPS61042DRBT is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications. It integrates a synchronous rectifier to improve efficiency and supports low input voltages, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 0.9 V to 5.5 V  
- **Adjustable Output Voltage:** Up to 5.5 V  
- **High Efficiency:** Up to 95% with synchronous rectification  
- **Low Quiescent Current:** 19 µA (typical) for extended battery life  
- **Integrated Synchronous Rectifier:** Eliminates the need for an external diode  
- **Fixed 1.2 MHz Switching Frequency:** Reduces external component size  
- **Automatic Power-Save Mode:** Enhances efficiency at light loads  
- **Thermal Shutdown & Overcurrent Protection:** Ensures device safety  
- **Small Package (VSON-8):** Space-saving for compact designs
