Description and Introduction

Active Clamp Current Mode PWM Controller The LM5026MT is a high-voltage PWM controller manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Input Voltage Range:** 10V to 100V  
- **Operating Frequency:** Adjustable up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Drive Current:** 1.5A (peak)  
- **Switching Topology:** Supports buck, boost, flyback, and forward converters  
- **Control Method:** Peak current mode control  
- **Protection Features:**  
  - Undervoltage lockout (UVLO)  
  - Overcurrent protection  
  - Thermal shutdown  
- **Package:** TSSOP-16  

### **Descriptions:**  
The LM5026MT is designed for high-voltage DC-DC power conversion applications. It integrates a high-voltage start-up regulator, reducing the need for external bias supplies. The controller is suitable for industrial, automotive, and telecom power systems.  

### **Features:**  
- Wide input voltage range (10V to 100V)  
- Adjustable oscillator frequency  
- Programmable soft-start  
- Synchronizable to an external clock  
- Precision reference voltage (1.25V)  
- Low shutdown current (<100µA)  

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