Description and Introduction

Dual High Efficiency SO-16 Step-Down Switching Regulator Controllers The LTC1143CS#TR is a high-efficiency switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 40V  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency:** Up to 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SOIC (SO-16)  
- **Control Method:** PWM (Pulse Width Modulation)  
- **Current Limit:** Adjustable  

### **Descriptions:**  
The LTC1143CS#TR is a synchronous step-down (buck) switching regulator controller designed for high-efficiency power conversion. It drives external N-channel MOSFETs to regulate output voltage with minimal power loss. The device includes features like soft-start, current limiting, and shutdown capability.  

### **Features:**  
- Synchronous rectification for improved efficiency  
- Adjustable output voltage  
- Low quiescent current  
- Soft-start function  
- Current limit protection  
- Shutdown mode for reduced power consumption  
- Wide input voltage range  

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