Description and Introduction

Secondary Side Dual Output Controller with Opto Driver The LT3804EFE is a synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 60V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable from 100kHz to 500kHz  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  
- **Control Method:** Current Mode  
- **Synchronous Rectification:** Yes  
- **Efficiency:** Up to 95%  

### **Descriptions:**  
The LT3804EFE is a high-performance, wide-input voltage range DC/DC controller designed for synchronous buck converters. It drives external N-channel MOSFETs and provides high efficiency power conversion. The device features adjustable frequency operation, current-mode control for fast transient response, and programmable soft-start.  

### **Features:**  
- Wide input voltage range (4.5V to 60V)  
- Adjustable output voltage down to 0.8V  
- Synchronous rectification for high efficiency  
- Programmable switching frequency (100kHz to 500kHz)  
- Current-mode control with adjustable slope compensation  
- Programmable soft-start  
- Low shutdown current (<1µA)  
- Overcurrent and overtemperature protection  
- 16-Lead TSSOP exposed pad package for thermal management  

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