Description and Introduction

3 The UCC383T-ADJ is a synchronous buck controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 300kHz (fixed)  
- **Output Current:** Up to 10A (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
The UCC383T-ADJ is a high-performance synchronous buck controller designed for DC-DC voltage regulation. It integrates PWM control with synchronous rectification to improve efficiency in step-down power supply applications.  

### **Features:**  
- **Synchronous Rectification:** Reduces power loss and improves efficiency.  
- **Adjustable Output Voltage:** Set via external feedback resistors.  
- **Fixed-Frequency Operation:** 300kHz PWM control for predictable noise performance.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Overcurrent Protection:** Safeguards against excessive load currents.  
- **Thermal Shutdown:** Protects the device from overheating.  

This information is based solely on TI's official documentation for the UCC383T-ADJ.
