Description and Introduction

Current Regulated Switched Capacitor LED Driver with Analog Brightness Control The LM2792LD-H is a dual white LED charge pump driver manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 30mA per LED (adjustable)  
- **Efficiency:** Up to 90%  
- **Switching Frequency:** 1MHz (typical)  
- **Package:** 10-pin LLP (Leadless Leadframe Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Dimming Control:** PWM or analog dimming  
- **Number of LEDs Supported:** 2 (dual output)  

### **Descriptions:**  
- The LM2792LD-H is designed to drive two white LEDs efficiently with a regulated current.  
- It uses a charge pump architecture to boost input voltage as needed.  
- The device includes built-in soft-start and thermal shutdown protection.  

### **Features:**  
- **Automatic Mode Switching:** Switches between 1x, 1.5x, and 2x modes for optimal efficiency.  
- **Low Noise Operation:** Minimizes EMI interference.  
- **High Accuracy Current Matching:** Ensures uniform brightness between LEDs.  
- **Small Footprint:** Suitable for space-constrained applications.  
- **Integrated Power MOSFETs:** Reduces external component count.  

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