Description and Introduction

36V, 2A, 2.8MHz Step-Down Switching Regulator with 50碌A Quiescent Current The LT3481EMSE is a step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.4V to 16V  
- **Output Voltage Range:** Up to 40V  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Maximum Output Current:** 1A (dependent on input/output conditions)  
- **Efficiency:** Up to 87%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead MSOP (Exposed Pad)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LT3481EMSE is a high-efficiency, fixed-frequency step-up DC/DC converter designed for applications requiring high output voltages. It includes an internal 1.5A, 40V switch and features a constant-frequency current-mode architecture for stable operation.  

### **Features:**  
- **Wide Input Voltage Range:** 2.4V to 16V  
- **Adjustable Output Voltage (Up to 40V)**  
- **1.2MHz Switching Frequency** (allows small external components)  
- **Internal Soft-Start** (reduces inrush current)  
- **Low Shutdown Current (<1µA)**  
- **Thermal Shutdown Protection**  
- **Current Mode Control** (improves transient response and loop stability)  
- **Synchronous Rectification Capability** (for higher efficiency)  

This device is commonly used in battery-powered systems, industrial applications, and automotive electronics where a high output voltage is required from a lower input voltage.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)

Description and Introduction

36V, 2A, 2.8MHz Step-Down Switching Regulator with 50碌A Quiescent Current The LT3481EMSE is a dual step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3.6V to 25V  
- **Output Voltage Range:** 0.8V to 20V (adjustable)  
- **Output Current:** Up to 2.1A per channel (total 4.2A)  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead MSOP (Exposed Pad)  

### **Descriptions:**
- The LT3481EMSE is a dual monolithic buck regulator with internal power switches.  
- It is designed for high efficiency and compact power supply solutions.  
- Each channel operates independently with adjustable output voltage.  
- Features Burst Mode® operation for improved efficiency at light loads.  

### **Features:**
- **Dual Independent Regulators:** Two step-down converters in one package.  
- **Low Quiescent Current:** 50µA per channel in Burst Mode.  
- **Synchronizable:** Can be synchronized to an external clock.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Short-Circuit Protection:** Includes cycle-by-cycle current limiting.  
- **Thermal Shutdown:** Protects against overheating.  
- **Small Footprint:** Suitable for space-constrained applications.
