Description and Introduction

Active Clamp Voltage Mode PWM Controller The LM5025CMTC is a high-voltage pulse width modulation (PWM) controller manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Input Voltage Range:** 15V to 100V  
- **Operating Frequency:** Adjustable up to 1MHz  
- **Output Drive Current:** 1A (peak)  
- **Duty Cycle Range:** Up to 95%  
- **UVLO (Undervoltage Lockout):** Adjustable  
- **Package:** TSSOP-16 (CMTC)  
- **Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The LM5025CMTC is designed for high-voltage DC-DC converter applications, including flyback, forward, and boost topologies. It features a high-voltage start-up regulator, reducing the need for an external bias supply. The controller includes cycle-by-cycle current limiting, soft-start, and thermal shutdown protection.  

### **Features:**  
- **High-Voltage Start-Up Regulator** (up to 100V)  
- **Programmable Oscillator Frequency**  
- **Current Mode Control**  
- **Adjustable Soft-Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Thermal Shutdown Protection**  
- **Synchronous Rectifier Control** (for improved efficiency)  
- **TSSOP-16 Package** (space-saving design)  

This information is based on the manufacturer's datasheet and technical documentation.
