Description and Introduction

Low Noise, High Efficiency, Inductorless Step-Down DC/DC Converter The LTC1911EMS8-1.8#PBF is a step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 1.8V (fixed)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Package:** 8-Lead MSOP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Dropout Operation:** Yes  
- **Quiescent Current:** 40µA (typical)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LTC1911 is a high-efficiency, synchronous step-down DC/DC converter optimized for low voltage applications. It integrates a power switch and synchronous rectifier, eliminating the need for an external Schottky diode. The fixed 1.8V output makes it suitable for powering low-voltage digital circuits.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency  
- **Burst Mode® Operation:** Enhances light-load efficiency  
- **Short-Circuit Protection:** Prevents damage during faults  
- **Low Dropout Mode:** Maintains regulation even when input voltage approaches output  
- **Thermal Shutdown:** Protects against overheating  
- **Small Footprint:** MSOP-8 package for space-constrained applications  

This regulator is commonly used in portable electronics, battery-powered devices, and embedded systems requiring a stable 1.8V supply.
