Description and Introduction

1.8-V Output, 400-mA, 95% Efficient Step-Down Converter, 15uA, ThinSOT-23 5-SOT -40 to 85 The TPS62222DDCTG4 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 0.6V to VIN  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin VSON (2mm x 2mm)  

### **Descriptions:**  
The TPS62222DDCTG4 is a high-efficiency, synchronous step-down DC-DC converter optimized for low-power applications. It operates at a fixed frequency of 2.25MHz, allowing the use of small external components. The device is designed for battery-powered systems, portable devices, and other space-constrained applications requiring high efficiency and low quiescent current.

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and reduces power loss.  
- **Power-Save Mode:** Enhances efficiency at light loads.  
- **100% Duty Cycle Operation:** Supports low dropout conditions.  
- **Soft Start:** Prevents inrush current during startup.  
- **Thermal Shutdown Protection:** Safeguards the device from overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This information is based on the manufacturer's datasheet for the TPS62222DDCTG4.
