Description and Introduction

Active Clamp Voltage Mode PWM Controller The LM5025AMTC is a high-voltage pulse width modulation (PWM) controller manufactured by Texas Instruments (NS). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 13V to 90V  
- **Operating Frequency Range:** 50kHz to 1MHz  
- **Duty Cycle Range:** Up to 95%  
- **Output Drive Current:** 1.5A (peak)  
- **UVLO (Undervoltage Lockout):** Adjustable  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-16 (AMTC)  

### **Descriptions:**
- The LM5025AMTC is designed for high-voltage DC-DC converter applications.  
- It includes a high-voltage start-up regulator, reducing the need for an external bias supply.  
- The device supports both voltage-mode and current-mode control topologies.  
- It is suitable for isolated and non-isolated power supply designs.  

### **Features:**
- **Wide Input Voltage Range:** Supports operation from 13V to 90V.  
- **Programmable Oscillator:** Allows frequency adjustment via external resistors.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Enhances protection.  
- **Synchronous Rectifier Control:** Supports efficient power conversion.  
- **High-Speed Gate Driver:** Optimized for fast switching.  
- **Thermal Shutdown Protection:** Prevents overheating.
