Description and Introduction

White LED Driver System with I2C Compatible Brightness Control The LM27964SQX-A is a white LED driver manufactured by National Semiconductor (NS).  

**Specifications:**  
- Input Voltage Range: 2.7V to 5.5V  
- Output Current: Up to 30mA per channel  
- Number of Channels: 6  
- Efficiency: Up to 90%  
- Switching Frequency: 1MHz (typical)  
- Package: 16-pin LLP (Leadless Leadframe Package)  
- Operating Temperature Range: -40°C to +85°C  

**Descriptions:**  
The LM27964SQX-A is a highly efficient charge pump-based LED driver designed for backlighting applications. It supports up to six white LEDs with independent current control, ensuring uniform brightness. The device operates in fractional charge pump modes (1x, 1.5x) to optimize efficiency based on input voltage and LED forward voltage requirements.  

**Features:**  
- Automatic mode switching (1x/1.5x) for optimal efficiency  
- Independent current sinks for each LED channel  
- Low dropout operation  
- Soft-start and inrush current limiting  
- Thermal shutdown protection  
- PWM dimming capability (up to 25kHz)  
- Small footprint and minimal external components required
