Description and Introduction

High Voltage, 3A,200kHz/100kHz Step-Down Switching Regulators The LT3430EFE-1 is a high voltage, high efficiency 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 60V  
- **Output Current:** Up to 2.5A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-16 (Exposed Pad)  

### **Descriptions:**
- The LT3430EFE-1 is a step-down (buck) switching regulator designed for high voltage applications.  
- It features a built-in NPN power switch and can operate with input voltages as high as 60V.  
- The regulator includes internal compensation, soft-start, and current limiting for robust performance.  

### **Features:**
- **Wide Input Voltage Range:** Supports 3.5V to 60V input.  
- **Adjustable Output Voltage:** Configurable from 1.24V to 60V.  
- **High Efficiency:** Up to 90% efficiency with minimal external components.  
- **Integrated Power Switch:** Reduces external component count.  
- **200kHz Switching Frequency:** Balances efficiency and component size.  
- **Thermal Protection:** Prevents overheating.  
- **Soft-Start Function:** Reduces inrush current at startup.  
- **Current Limit Protection:** Safeguards against overloads.  

The LT3430EFE-1 is suitable for industrial, automotive, and telecom applications requiring high voltage regulation.
