Description and Introduction

Dual Display White LED Driver with I2C Compatible Brightness Control The LM27965SQX is a dual white LED driver manufactured by National Semiconductor (NS). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 32mA per channel (adjustable)  
- **Number of Channels:** 2  
- **Efficiency:** Up to 90%  
- **Switching Frequency:** 1MHz (typical)  
- **Dimming Control:** PWM (Pulse Width Modulation) or analog  
- **Package:** 16-pin LLP (Leadless Leadframe Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The LM27965SQX is designed to drive dual white LEDs for backlighting applications in portable devices.  
- It integrates a high-efficiency charge pump and current regulators to provide stable LED current.  
- The device supports both PWM and analog dimming for brightness control.  

### **Features:**  
- **Dual Independent LED Drivers:** Allows precise current control for two LEDs.  
- **1x/1.5x Charge Pump Modes:** Optimizes efficiency based on input voltage.  
- **Low Dropout Current Regulators:** Ensures consistent brightness even at low battery levels.  
- **Soft-Start Circuitry:** Prevents inrush current during startup.  
- **Thermal Shutdown Protection:** Safeguards the device from overheating.  
- **Small Footprint:** Suitable for space-constrained designs.  

This information is based solely on the manufacturer's datasheet.
