Description and Introduction

Dual 1.3A White LED Step-Up Converters with Wide Dimming The LT3486EDHC is a dual step-down switching regulator IC manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 0.8V to 34V  
- **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 DFN (5mm × 3mm × 0.75mm)  
- **Features:**  
  - Dual independent regulators  
  - Synchronous rectification  
  - Adjustable soft-start  
  - Power good flag  
  - Overcurrent and thermal protection  
  - Low shutdown current (<1µA)  

### **Descriptions and Features:**  
The LT3486EDHC is a high-efficiency, dual-channel step-down switching regulator designed for applications requiring multiple regulated outputs. It integrates two independent regulators with synchronous rectification, minimizing external component count. The fixed 1.2MHz switching frequency allows for compact designs while maintaining high efficiency.  

Key features include adjustable soft-start for controlled power-up sequencing, a power good indicator for monitoring output stability, and built-in protection against overcurrent and overheating. The device is suitable for automotive, industrial, and telecom applications where high input voltage and dual outputs are required.  

(Note: Ensure to verify datasheet details for exact specifications in your application.)
