Description and Introduction

2.5A, 4MHz, Monolithic Synchronous Step-Down Regulator The LTC3412IFE#PBF is a high-efficiency, monolithic synchronous buck regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.25V to 5.5V  
- **Output Voltage Range:** 0.8V to 5V (adjustable)  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 1.25MHz or 2.25MHz (selectable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  

### **Descriptions:**
- The LTC3412IFE#PBF is a synchronous step-down DC/DC converter designed for high-performance applications requiring high efficiency and compact size.  
- It uses a constant-frequency, current-mode architecture for stable operation under varying load conditions.  
- The device includes internal power switches, reducing the need for external components.  

### **Features:**
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Selectable Frequency:** Allows optimization for efficiency or component size.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage approaches the output voltage.  
- **Power Good Output:** Provides a signal indicating the output voltage is within regulation.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Short-Circuit Protection:** Enhances reliability under fault conditions.  
- **Burst Mode® Operation:** Improves efficiency at light loads.  

The LTC3412IFE#PBF is commonly used in portable electronics, point-of-load regulation, and distributed power systems.
