Description and Introduction

28-V, 85% Efficient Boost Converter in QFN-8, Digitally Adjustable 8-SON -40 to 85 The TPS61045DRBRG4 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:** 1.8 V to 5.5 V  
- **Output Voltage Range:** Adjustable from 2.5 V to 5.5 V  
- **Output Current:** Up to 1.2 A (switch current limit)  
- **Switching Frequency:** 1.2 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSON-8 (DRB)  

### **Descriptions:**  
The TPS61045DRBRG4 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 suitable for powering portable electronics, IoT devices, and other low-power systems requiring a regulated voltage higher than the input supply.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Low Quiescent Current:** 19 µA (typical) for improved battery life.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This information is based solely on the manufacturer's datasheet. For detailed application guidelines, refer to the official TI documentation.

Application Scenarios & Design Considerations

28-V, 85% Efficient Boost Converter in QFN-8, Digitally Adjustable 8-SON -40 to 85

Alternative Part Number

  • TPS61040DBVR --: Same TPS6104x boost converter family in a SOT-23-5 package, functionally similar boost driver with comparable input range and switching behavior.
  • TPS61041DBVR --: Sister device in the TPS6104x family with similar boost converter topology and pin-compatible SOT-23-5 footprint, suitable for many of the same applications.
  • LT1932ES6#PBF --: Alternative boost converter IC from a different vendor with comparable boost regulation function, usable as a cross-vendor replacement after verifying voltage and current ratings.
  • TPS61045DRBR --: Same boost converter family and identical DRB package, but without the G4 lead-free suffix; functionally equivalent and widely available.
