Description and Introduction

1A Low Noise High Current LED Charge Pump with Independent Torch/Flash Current Control The LTC3216EDE is a charge pump LED driver manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC3216EDE  
- **Package:** 16-Lead DFN (Dual Flat No-Lead)  
- **Input Voltage Range:** 2.9V to 5.5V  
- **Output Current:** Up to 150mA per LED (total of 600mA for four channels)  
- **Number of LED Channels:** 4  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Dimming Control:** 128 linear steps (7-bit)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The LTC3216EDE is a high-efficiency, low-noise charge pump LED driver designed to power up to four white LEDs. It features a 1x/1.5x charge pump architecture, allowing it to regulate LED current with minimal input ripple. The device includes automatic mode switching to optimize efficiency based on input voltage and LED forward voltage requirements.

### **Features:**
- **Automatic Mode Switching:** Switches between 1x and 1.5x modes for optimal efficiency.  
- **Low Noise Operation:** Minimizes EMI with constant frequency switching.  
- **Independent LED Current Control:** Each of the four channels can be individually controlled.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Thermal Protection:** Includes overtemperature shutdown.  
- **Small Footprint:** DFN package saves board space.  

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