Description and Introduction

Photoflash Capacitor Charger The LT3484EDCB-2 is a dual step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.6V to 16V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 1.4A per channel (2.8A total)  
- **Switching Frequency:** 1.2MHz (synchronizable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions:**  
- Dual monolithic synchronous buck regulator with independent channels.  
- Operates in forced continuous, pulse-skipping, or Burst Mode® for improved efficiency.  
- Includes internal power switches, synchronous rectifiers, and compensation.  
- Low dropout operation (100% duty cycle).  

### **Features:**  
- **Independent Channels:** Each channel has its own feedback and control loop.  
- **Synchronizable:** Can sync to an external clock.  
- **Low Quiescent Current:** 40μA per channel in Burst Mode.  
- **Soft-Start & Tracking:** Reduces inrush current.  
- **Short-Circuit Protection:** Hiccup mode for fault recovery.  
- **Thermal Shutdown:** Protects against overheating.
