Description and Introduction

High Power No RSENSE Current Mode Synchronous Step-Down Switching Regulator The LTC1775CS#PBF is a high-efficiency synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** 0.8V to 5V (adjustable via external resistors)  
- **Switching Frequency:** Up to 550kHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 16-Lead SOIC (SO-16)  
- **Control Method:** Current-mode PWM  
- **Synchronous Rectification:** Yes (reduces power loss)  
- **Low Dropout Operation:** Allows 100% duty cycle  
- **Protection Features:** Overcurrent, undervoltage lockout (UVLO), and thermal shutdown  

### **Descriptions:**  
The LTC1775CS#PBF is designed for high-efficiency step-down DC/DC conversion, ideal for battery-powered and industrial applications. It drives external N-channel MOSFETs to minimize conduction losses and supports adjustable output voltage and switching frequency.  

### **Features:**  
- High-efficiency synchronous operation  
- Wide input voltage range (4V to 36V)  
- Adjustable output voltage (0.8V to 5V)  
- Programmable switching frequency (up to 550kHz)  
- Low dropout operation (100% duty cycle)  
- Current-mode control for fast transient response  
- Integrated protection features (UVLO, overcurrent, thermal shutdown)  
- 16-Lead SOIC package  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to Linear Technology’s official documentation.
