Description and Introduction

High Voltage/ 3A/ 200kHz Step-Down Switching Regulator The LT3430EFE is a step-down switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3.5V to 60V  
- **Output Voltage Range:** Adjustable from 1.24V to 57V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  

### **Descriptions:**
The LT3430EFE is a high-efficiency, monolithic step-down DC/DC converter designed for applications requiring high input voltage and high output current. It features an internal 3A switch and can operate with input voltages up to 60V. The regulator uses a current-mode architecture for fast transient response and stable operation.  

### **Features:**
- Wide input voltage range (3.5V to 60V)  
- Adjustable output voltage (1.24V to 57V)  
- High output current capability (3A)  
- Low dropout operation (100% duty cycle)  
- Internal soft-start for controlled startup  
- Current-mode control for improved transient response  
- Thermal shutdown and current limit protection  
- Available in a thermally enhanced TSSOP package  

This regulator is commonly used in automotive, industrial, and telecom applications where high input voltages and efficient power conversion are required.
