Description and Introduction

SMBus Dual High Side Switch Controller The LTC1623CMS8 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 VIN  
- **Switching Frequency:** Up to 350kHz  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** MSOP-8  
- **Topology:** Synchronous Buck (Step-Down)  
- **Efficiency:** Up to 95%  
- **Current Limit:** Adjustable  
- **Duty Cycle Range:** 0% to 100%  

### **Descriptions:**  
The LTC1623CMS8 is designed to drive N-channel MOSFETs in a synchronous buck converter configuration. It provides high efficiency power conversion with minimal external components. The controller features adjustable current limiting, soft-start, and can operate in continuous or discontinuous mode.  

### **Features:**  
- **Synchronous Operation:** Reduces power loss by replacing the Schottky diode with a MOSFET.  
- **Adjustable Current Limit:** Enhances flexibility for different load conditions.  
- **Wide Input Voltage Range:** Supports 4V to 36V input.  
- **Low Dropout Operation:** Allows 100% duty cycle for low dropout conditions.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Short-Circuit Protection:** Improves reliability under fault conditions.  
- **Thermal Shutdown:** Protects the device from overheating.
