Description and Introduction

PWM Controller with Integrated Half-Bridge and SyncFET Drivers The LM5035CMH is a high-voltage PWM controller manufactured by National Semiconductor (NS). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Switching Frequency Range:** 50kHz to 1MHz  
- **Maximum Duty Cycle:** 50% (Push-Pull Topology)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
- The LM5035CMH is designed for high-voltage, high-efficiency power conversion applications.  
- It supports push-pull, half-bridge, and full-bridge topologies.  
- Features an integrated high-voltage start-up regulator, eliminating the need for an external bias supply.  

### **Features:**  
- **Integrated High-Voltage Start-Up Regulator:** Operates directly from the input voltage (up to 100V).  
- **Programmable Oscillator:** Adjustable switching frequency (50kHz to 1MHz).  
- **Precision Reference:** 2.5V ±1% accuracy.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Error Amplifier:** Supports voltage-mode control.  
- **Current-Limit Protection:** Enhances system reliability.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

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