Description and Introduction

1.8V, 1.5MHz, 300mA Synchronous Step-Down Regulators in ThinSOT The LTC3405AES6-1.8#TRMPBF is a synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 20μA (typical) in Burst Mode operation  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  
- **Topology:** Synchronous Buck (Step-Down)  
- **Features:**  
  - Burst Mode operation for high efficiency at light loads  
  - Low dropout operation  
  - Internal soft-start  
  - Short-circuit protection  
  - Thermal shutdown  

### **Descriptions:**  
The LTC3405AES6-1.8 is a high-efficiency, synchronous step-down DC/DC converter optimized for portable applications. It operates from a single Li-Ion cell or other low-voltage sources and provides a fixed 1.8V output. The high switching frequency allows the use of small external components, making it suitable for space-constrained designs.  

### **Features:**  
- **Burst Mode Operation:** Enhances efficiency at light loads.  
- **Low Dropout:** Allows operation close to the input voltage.  
- **Internal Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Short-Circuit & Thermal Protection:** Ensures safe operation under fault conditions.  
- **Small Footprint:** SOT-23-6 package saves board space.  

This device is commonly used in battery-powered applications, portable devices, and other low-power systems requiring a regulated 1.8V supply.
