Description and Introduction

Isolated No-Opto Synchronous Flyback Controller with Wide Input Supply Range The LT3825EFE#PBF is a switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 60V  
- **Output Voltage Range:** Adjustable  
- **Switching Frequency:** Programmable (100kHz to 500kHz)  
- **Topology:** Flyback, Forward, or SEPIC  
- **Gate Drive Current:** 1.5A (peak)  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  
- **Duty Cycle Range:** Up to 96%  

### **Descriptions:**  
The LT3825EFE#PBF is a high-performance current-mode PWM controller designed for isolated power supply applications. It includes features for precise regulation, fault protection, and high-efficiency operation.  

### **Features:**  
- **Current-Mode Control:** Ensures stable operation with fast transient response.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Synchronizable Switching Frequency:** Allows synchronization to an external clock.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Adjustable Line Undervoltage Protection:** Prevents operation below a set input voltage threshold.  
- **Wide Input Voltage Range:** Supports various power supply designs.  

This controller is commonly used in telecom, industrial, and automotive applications requiring isolated power conversion.
