Description and Introduction

Dual Monolithic 1.4A Step-Down Switching Regulator The LT3508IUF#PBF is a monolithic step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 1.22V to 35V  
- **Output Current:** Up to 2.5A  
- **Switching Frequency:** 575kHz  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 24-Lead QFN (4mm x 4mm)  
- **Features:**  
  - Internal 2.5A Switch  
  - Adjustable Soft-Start  
  - Programmable Current Limit  
  - Low Dropout Operation (100% Duty Cycle)  
  - Synchronizable to an External Clock  
  - Thermal Shutdown Protection  

### **Descriptions and Features:**  
The LT3508IUF#PBF is a high-performance step-down DC/DC converter designed for applications requiring high efficiency and compact size. It integrates a 2.5A power switch and operates over a wide input voltage range, making it suitable for automotive, industrial, and battery-powered systems.  

Key features include:  
- **Wide Input Range:** Supports 4V to 36V operation.  
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Adjustable Output:** Allows flexibility in setting the desired output voltage.  
- **Protection Features:** Includes thermal shutdown and programmable current limit.  
- **Low Dropout Mode:** Enables operation even when the input voltage is close to the output.  
- **Synchronization Capability:** Can be synchronized to an external clock for noise-sensitive applications.  

This regulator is ideal for powering FPGAs, microprocessors, and other high-performance loads in demanding environments.
