Description and Introduction

100V Push-Pull Current Mode PWM Controller The LM5030 is a high-voltage pulse-width modulation (PWM) controller manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Drive Current:** 1.5A (peak)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SOIC-16, WQFN-16  

### **Descriptions:**  
The LM5030 is designed for high-voltage DC-DC converter applications, including isolated and non-isolated topologies. It integrates a high-voltage startup regulator, PWM controller, and gate driver, making it suitable for power supply designs in industrial, telecom, and automotive systems.  

### **Features:**  
- **High-Voltage Startup Regulator:** Eliminates the need for an external bias supply.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Provides protection against overloads.  
- **Synchronizable Oscillator:** Allows synchronization with an external clock.  
- **Error Amplifier:** Supports voltage-mode control with adjustable compensation.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

The LM5030 is optimized for efficiency and reliability in high-voltage power conversion applications.
