Description and Introduction

36V, 2A, 2.8MHz Step-Down Switching Regulator with 50碌A Quiescent Current The LT3481EMSE#PBF is a dual step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 3.6V to 36V  
- **Output Voltage Range:** Adjustable from 1.25V to 35V  
- **Output Current:** Up to 2.5A per channel  
- **Switching Frequency:** 1.1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead MSOP (Exposed Pad)  
- **Features:**  
  - Dual independent step-down regulators  
  - Low dropout operation (100% duty cycle)  
  - Adjustable soft-start  
  - Power good indicator  
  - Synchronizable switching frequency  
  - Overcurrent and overtemperature protection  

### **Descriptions and Features:**  
The LT3481EMSE#PBF is a high-efficiency, dual-channel step-down DC/DC converter designed for applications requiring multiple regulated voltages. It operates from a wide input voltage range, making it suitable for automotive, industrial, and battery-powered systems.  

- **Dual Independent Regulators:** Allows two separate output voltages.  
- **High Efficiency:** Minimizes power loss with synchronous rectification.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Adjustable Soft-Start:** Prevents inrush current at startup.  
- **Synchronizable:** Can be synchronized to an external clock to reduce noise.  
- **Protection Features:** Includes overcurrent and thermal shutdown for reliability.  

This regulator is ideal for distributed power systems, industrial controls, and automotive applications where multiple regulated voltages are needed.
