Description and Introduction

8-Pin N-FET Linear Regulator Controller 8-SOIC -40 to 85 The UCC2837DG4 is a high-speed synchronous buck controller manufactured by Texas Instruments (TI)/Burr-Brown (BB). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable down to 1.25V  
- **Switching Frequency:** Up to 1MHz  
- **Output Current:** Controller (requires external FETs)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The UCC2837DG4 is a synchronous buck PWM controller designed for high-efficiency DC-DC conversion. It provides precise voltage regulation and supports high-frequency operation, making it suitable for power supply applications in computing, telecommunications, and industrial systems.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by replacing the diode with a low-side MOSFET.  
- **Adjustable Output Voltage:** Set via external resistor divider.  
- **High-Speed Operation:** Up to 1MHz switching frequency for compact designs.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage limits.  
- **Current Mode Control:** Provides fast transient response and simplified loop compensation.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
