Description and Introduction

100V Current Mode PWM Controller The LM5020SD-2 is a high-voltage PWM controller manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Input Voltage Range:** 13V to 90V  
- **Operating Frequency:** Adjustable up to 1MHz  
- **Output Drive Current:** 1.5A (peak)  
- **Duty Cycle Range:** Up to 95%  
- **Switching Topology:** Supports flyback, forward, and boost converters  
- **Package:** 10-pin WSON (SD)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Overcurrent protection, undervoltage lockout (UVLO), and thermal shutdown  

### **Descriptions:**  
The LM5020SD-2 is a high-performance PWM controller designed for high-voltage DC-DC applications. It integrates a high-voltage startup regulator, reducing the need for an external bias supply.  

### **Features:**  
- **High-Voltage Startup Regulator:** Eliminates the need for an external bias supply.  
- **Adjustable Soft-Start:** Reduces inrush current during startup.  
- **Programmable Oscillator:** Allows flexible frequency setting.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Current Mode Control:** Improves transient response and simplifies loop compensation.  

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