Description and Introduction

600mA Low Noise Multi-LED Camera Light Charge Pumps The LTC3217EUD is a high-efficiency, low-noise charge pump LED driver manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.9V to 5.5V  
- **Output Current:** Up to 150mA per LED (total 450mA)  
- **Number of LED Channels:** 3  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Dimming Control:** Analog (via external resistor) or PWM  
- **Low Noise Operation:** Low ripple for sensitive applications  
- **Thermal Protection:** Yes  
- **Package:** 16-Lead QFN (4mm x 4mm)  

### **Descriptions:**  
The LTC3217EUD is designed to drive up to three white LEDs with constant current, making it suitable for backlighting and general LED illumination. It uses a charge pump architecture to boost input voltage efficiently without requiring an inductor.  

### **Features:**  
- No inductors required (charge pump topology)  
- Low noise and low ripple  
- Independent current control for each LED  
- Soft-start to limit inrush current  
- Thermal shutdown protection  
- Small footprint QFN package  

This information is based solely on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
