Description and Introduction

Boost, Flyback, SEPIC and Inverting Controller The LT3757EMSE is a high voltage, high-side current sense 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 100V  
- **Output Voltage Range**: Up to 100V  
- **Switching Frequency Range**: 100kHz to 1MHz  
- **Current Sense Threshold**: Adjustable (50mV typical)  
- **Operating Temperature Range**: -40°C to +125°C  
- **Package**: 16-Lead MSOP (Exposed Pad)  

### **Descriptions**:
- The LT3757EMSE is a versatile DC/DC controller designed for high-voltage applications, including LED drivers, battery charging, and power supplies.  
- It supports boost, flyback, SEPIC, and buck-boost topologies.  
- The device includes a high-side current sense amplifier for accurate current regulation.  
- It features a wide input voltage range, making it suitable for automotive, industrial, and telecom applications.  

### **Features**:
- **Wide Input Voltage Range**: Operates from 4.5V to 100V.  
- **Adjustable Frequency**: Allows optimization for efficiency and component size.  
- **High-Side Current Sensing**: Eliminates the need for a low-side sense resistor.  
- **Programmable Soft-Start**: Reduces inrush current.  
- **Synchronizable Switching Frequency**: Minimizes noise interference.  
- **Thermal Shutdown Protection**: Prevents overheating.  
- **Adjustable Current Limit**: Enhances system protection.
