Description and Introduction

75V, Secondary Side Post Regulator/ Synchronous Buck Controller 16-WSON The LM5115SDX/NOPB is a dual synchronous buck controller manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 75V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 50kHz to 500kHz  
- **Driver Output Current:** 2A (peak source/sink)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Pin WSON (Exposed Pad)  

### **Descriptions:**  
- Designed for high-efficiency synchronous buck converters.  
- Supports wide input voltage range for industrial and automotive applications.  
- Features adaptive gate drive timing for optimal efficiency.  
- Includes adjustable soft-start and cycle-by-cycle current limiting.  

### **Features:**  
- **Dual N-Channel MOSFET Drivers** (independent high-side and low-side drivers).  
- **Programmable Dead-Time Control** for minimizing body diode conduction losses.  
- **Voltage Feed-Forward Compensation** for improved line transient response.  
- **Precision 1.5% Voltage Reference** for accurate output regulation.  
- **Hiccup Mode Overcurrent Protection** for fault recovery.  
- **Synchronizable to External Clock** for noise-sensitive applications.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official NSC documentation.
