Description and Introduction

Dual 1.3A White LED Step-Up Converters with Wide Dimming The LT3486EFE#PBF is a dual monolithic step-down switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3.6V to 36V  
- **Output Voltage Range:** Adjustable from 1.22V to 35V  
- **Output Current per Channel:** Up to 2.1A  
- **Switching Frequency:** 1.4MHz (fixed)  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  
- **Topology:** Synchronous Buck Regulator  
- **Protection Features:** Overcurrent, Overtemperature, and Undervoltage Lockout  

### **Descriptions:**  
The LT3486EFE#PBF is a high-efficiency, dual-channel step-down DC/DC converter with integrated power switches. It is designed for applications requiring compact, high-performance power conversion. The device operates at a fixed switching frequency of 1.4MHz, allowing the use of small external components.  

### **Features:**  
- Dual independent step-down regulators in one package  
- Synchronous rectification for high efficiency  
- Adjustable output voltage via external resistors  
- Low dropout operation (100% duty cycle)  
- Internal soft-start reduces inrush current  
- Shutdown current <1µA  
- Current-mode control for fast transient response  
- Thermally enhanced TSSOP-16 package  

This information is based on the manufacturer's datasheet and technical documentation.
