Description and Introduction

High Voltage 3A, 200kHz Step-Down Switching Regulator with 100碌A Quiescent Current The LT3434IFE is a high voltage, high efficiency switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 3.5V to 60V  
- **Output Voltage Range:** Adjustable from 1.25V to 55V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP  

### **Descriptions:**  
The LT3434IFE is a step-down (buck) switching regulator designed for high voltage applications. It features an internal 0.5A switch and can operate from input voltages as high as 60V. The regulator includes a low dropout mode for improved efficiency at low input-output differentials.  

### **Features:**  
- Wide input voltage range (3.5V to 60V)  
- Adjustable output voltage (1.25V to 55V)  
- Low shutdown current (<1µA)  
- Internal soft-start  
- Current mode control for improved transient response  
- Thermal shutdown protection  
- Short-circuit and overcurrent protection  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to Analog Devices' official documentation.
