Description and Introduction

1.8V / 300mA Step-Down Converter in 2x2mm SON/TSOT23 Package 6-WSON -40 to 85 The TPS62243DRVR is a synchronous step-down DC-DC converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 6-pin WSON (DRV)  

### **Descriptions:**  
- The TPS62243DRVR is a high-efficiency, low-quiescent-current buck converter optimized for battery-powered applications.  
- It operates in pulse-frequency modulation (PFM) mode at light loads to improve efficiency.  
- The device integrates synchronous rectification for high efficiency and requires minimal external components.  

### **Features:**  
- **Low Quiescent Current:** 17µA (typical) for extended battery life.  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Fixed-Frequency Operation:** 2.25MHz allows for small external components.  
- **100% Duty Cycle Mode:** Supports low dropout operation.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation.  
- **Small Package:** 6-pin WSON (2mm x 2mm) for space-constrained designs.
