Description and Introduction

5V, 400mA, 4MHz Step-Up DC/DC Converter 6-WSON The TPS61240DRVR is a synchronous boost converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Output Current:** Up to 1.2A (at 3.3V output from a 1.8V input)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin WSON (DRV)  

### **Description:**  
The TPS61240DRVR is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications. It supports very low input voltages (down to 0.7V) and provides a regulated output voltage up to 5.5V. The device integrates synchronous rectification for improved efficiency and is suitable for space-constrained applications due to its small package size.  

### **Features:**  
- **Ultra-Low Input Voltage Operation:** Starts up from 0.7V.  
- **High Efficiency:** Up to 95% with synchronous rectification.  
- **Low Quiescent Current:** 15µA (typical) for extended battery life.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Automatic Power Save Mode:** Enhances efficiency at light loads.  
- **Overcurrent and Thermal Protection:** Built-in safeguards.  
- **Small Footprint:** 6-pin WSON package (2mm x 2mm).
