Description and Introduction

High Voltage, 1.5A, 500kHz Step-Down Switching Regulators The LT1956IGN-5#PBF is a switching regulator IC manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 3.6V to 25V  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 200kHz (adjustable with external components)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead SSOP  

### **Descriptions:**  
The LT1956IGN-5#PBF is a step-down (buck) switching regulator designed for high-efficiency power conversion. It integrates a high-side switch and provides a fixed 5V output with minimal external components.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 3.6V to 25V input.  
- **High Efficiency:** Up to 90%, reducing power dissipation.  
- **Adjustable Switching Frequency:** Can be set via external components.  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output.  
- **Thermal Protection:** Includes thermal shutdown for safety.  
- **Current Limit Protection:** Prevents damage from excessive load current.  
- **Soft-Start Function:** Reduces inrush current during startup.  

This regulator is suitable for applications requiring stable 5V power from a higher input voltage source, such as industrial, automotive, and telecommunications systems.
