Description and Introduction

Adjustable, 300-mA, 95% Efficient Step-Down Converter in SOT-23 The TPS62200DBVT is a step-down DC-DC converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.7V to VIN (fixed options available)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- The TPS62200DBVT is a high-efficiency, low-quiescent-current synchronous step-down converter.  
- It is designed for battery-powered portable applications requiring extended battery life.  
- The device operates in PWM mode for higher load currents and automatically switches to PFM mode at light loads for improved efficiency.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **100% Duty Cycle Mode:** Allows operation at very low input voltages.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage approaches the output voltage.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

This information is based solely on the manufacturer's datasheet.
