Description and Introduction

High Input Voltage, Boost, Flyback, SEPIC and Inverting Controller The LT3758AEMSE#PBF is a high voltage, high current step-up (boost) DC/DC controller manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage Range:** Up to 100V (adjustable)  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Peak Switch Current Limit:** 5A  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead MSOP (Exposed Pad)  
- **Duty Cycle:** Up to 94%  

### **Descriptions:**
- The LT3758AEMSE#PBF is designed for driving N-channel MOSFETs in boost, flyback, SEPIC, and other topologies.  
- It features a wide input voltage range, making it suitable for automotive, industrial, and battery-powered applications.  
- The device includes a programmable soft-start, frequency synchronization, and current-mode control for stable operation.  

### **Features:**
- **High Voltage Capability:** Supports output voltages up to 100V.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Current-Mode Control:** Ensures stable loop response and fast transient performance.  
- **Programmable Soft-Start:** Prevents inrush current issues.  
- **Synchronization Input:** Allows external clock synchronization.  
- **Low Shutdown Current:** <1µA when disabled.  
- **Integrated Gate Driver:** Simplifies MOSFET driving.  

This IC is commonly used in LED drivers, battery charging, and high-voltage power supplies.
