Description and Introduction

Constant Frequency Current Mode Flyback DC/DC Controller in ThinSOT The LTC3803ES6-3 is a high-efficiency, current-mode synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** 300kHz  
- **Maximum Duty Cycle:** 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
- Designed for high-efficiency DC/DC conversion.  
- Operates in current-mode control for improved transient response.  
- Supports synchronous rectification for higher efficiency.  
- Features a low shutdown current (<1µA).  

### **Features:**  
- **Current-Mode Control:** Ensures stable operation and fast transient response.  
- **Synchronous Operation:** Reduces power loss by replacing the external Schottky diode with a MOSFET.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Wide Input Range:** Suitable for various power supply applications.  
- **Low Quiescent Current:** Enhances efficiency in light-load conditions.  
- **Short-Circuit Protection:** Improves system reliability.  

This information is based solely on the manufacturer's datasheet.
