Description and Introduction

High Efficiency Thermoelectric Cooler Controller The **LTC1923EGN#PBF** is a **synchronous DC/DC controller** manufactured by **Linear Technology** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Switching Frequency:** 50kHz to 500kHz (programmable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP (Narrow)  
- **Topology:** Synchronous Buck Controller  
- **Efficiency:** Up to 95% (depending on external components)  
- **Current Limit:** Adjustable  
- **Duty Cycle Range:** 0% to 100%  

### **Descriptions:**  
- The **LTC1923EGN#PBF** is a high-efficiency, synchronous step-down DC/DC controller designed for driving N-channel MOSFETs in buck converter applications.  
- It operates over a wide input voltage range, making it suitable for industrial, automotive, and telecom power supplies.  
- The device includes adjustable current limiting, soft-start, and programmable switching frequency.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by replacing the Schottky diode with a MOSFET.  
- **Programmable Frequency:** Allows optimization for efficiency or component size.  
- **Adjustable Current Limit:** Protects against overload conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Dropout Operation:** Supports 100% duty cycle for low input-output differentials.  
- **Wide Input Range:** Suitable for battery-powered and industrial applications.  
- **Thermally Enhanced Package:** 16-Lead SSOP for improved heat dissipation.  

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