Description and Introduction

3.5MHz, 1.5A, 92% Efficient Boost Converter with Adjustable Input Current Limit 8-WSON The TPS61252DSGT is a step-up (boost) DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.7V 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:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin WSON (DSG)  

### **Description:**  
The TPS61252DSGT is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications. It supports very low input voltages (as low as 0.7V) and provides a regulated output voltage up to 5.5V. The device integrates a synchronous rectifier to improve efficiency and reduce external component count.  

### **Features:**  
- **Ultra-Low Start-Up Voltage:** As low as 0.7V  
- **Automatic Power Path Management:** Seamless transition between battery and external power sources  
- **True Disconnect in Shutdown Mode:** Prevents battery drain  
- **Integrated Synchronous Rectifier:** Improves efficiency  
- **Fixed and Adjustable Output Voltage Options**  
- **Thermal Shutdown and Overcurrent Protection**  

This device is suitable for applications such as energy harvesting, portable electronics, and battery-powered IoT devices.
