Description and Introduction

28-V, 85% Efficient Boost Converter in QFN-8 for LCD Applications The TPS61045DRBT is a boost converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.9V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 19µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SON-6 (DRB)  

### **Descriptions:**  
The TPS61045DRBT is a high-efficiency, low-power 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:**  
- **Wide Input Voltage Range:** Supports operation from 0.9V to 5.5V.  
- **Adjustable Output Voltage:** Configurable via an external resistor divider.  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Thermal Shutdown Protection:** Safeguards the device from overheating.  
- **Small Footprint:** 6-pin SON package (2mm x 2mm) for space-constrained designs.  

This information is based on TI's official datasheet for the TPS61045DRBT.
