Description and Introduction

Low noise, high efficiency, inductorless step-down DC/DC converter. The LTC1911EMS8-1.8 is a step-down switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **LT (Linear Technology)**  

### **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:** MSOP-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Dropout Operation:** 100% duty cycle  
- **Quiescent Current:** 20µA (typical) in shutdown mode  

### **Descriptions:**  
- The LTC1911EMS8-1.8 is a high-efficiency, synchronous step-down DC/DC converter optimized for low voltage applications.  
- It integrates both main and synchronous switches, reducing external component count.  
- Designed for battery-powered and portable devices requiring a regulated 1.8V supply.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and reduces power loss.  
- **Burst Mode® Operation:** Enhances light-load efficiency.  
- **Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Low Dropout Mode:** Allows operation even when input voltage approaches output voltage.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Small Footprint:** MSOP-8 package saves board space.  

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

Description and Introduction

Low noise, high efficiency, inductorless step-down DC/DC converter. The LTC1911EMS8-1.8 is a synchronous step-down DC/DC converter 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%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead MSOP  

### **Descriptions & Features:**  
- **Synchronous Operation:** Reduces power loss by eliminating the need for an external Schottky diode.  
- **Low Dropout Operation:** Allows the output to remain in regulation even when the input voltage approaches the output voltage.  
- **Burst Mode® Operation:** Improves efficiency at light loads by reducing switching losses.  
- **Internal Soft-Start:** Limits inrush current during startup.  
- **Short-Circuit Protection:** Safeguards the device under fault conditions.  
- **Low Quiescent Current:** Typically 20µA in shutdown mode.  
- **Compact Solution:** Minimal external components required.  

This IC is commonly used in portable devices, battery-powered applications, and distributed power systems.
