Advanced Voltage Mode Pulse Width Modulator 14-PDIP -40 to 85 The UCC25702NG4 is a synchronous buck controller manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 42V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency Range:** 100kHz to 1MHz  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SOIC-16 (NG4)  

### **Descriptions:**  
- The UCC25702NG4 is a high-performance synchronous buck controller designed for DC-DC power conversion applications.  
- It supports both fixed-frequency and frequency synchronization modes.  
- The controller features adaptive dead-time control for improved efficiency and supports external synchronization.  

### **Features:**  
- **Adaptive Dead-Time Control:** Optimizes efficiency by minimizing body diode conduction losses.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Frequency Synchronization:** Allows synchronization to an external clock.  
- **Pre-Biased Output Startup:** Prevents negative current flow during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overload conditions.  
- **Low Quiescent Current:** Enhances efficiency in light-load conditions.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  

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