Description and Introduction

1.5-V Output, 300-mA, 95% Efficient Step-Down Converter in SOT-23 The TPS62201DBVRG4 is a step-down DC-DC converter manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable from 0.7V to VIN  
- **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  

### **Descriptions:**  
The TPS62201DBVRG4 is a high-efficiency, step-down synchronous DC-DC converter optimized for battery-powered applications. It operates in pulse-frequency modulation (PFM) mode at light loads to improve efficiency and switches to pulse-width modulation (PWM) mode for higher load conditions.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and reduces external component count.  
- **100% Duty Cycle Mode:** Ensures 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.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This device is commonly used in portable electronics, battery-powered systems, and other applications requiring efficient power conversion.
