Description and Introduction

1.875-V Output, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 The TPS62228DDCT is a step-down DC-DC converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable (0.6V to VIN)  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6 (DDC)  

### **Descriptions:**  
The TPS62228DDCT is a high-efficiency, synchronous step-down converter designed for battery-powered applications. It operates at a fixed frequency of 2.25MHz, allowing the use of small external components. The device supports a wide input voltage range, making it suitable for single-cell Li-ion or multi-cell alkaline/NiMH battery-powered systems.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **100% Duty Cycle Mode:** Allows operation at very low input voltages.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **Internal Soft Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.
