Description and Introduction

120mA High Efficiency Step-Down Switched Capacitor Voltage Converter with Voltage Monitoring The LM2798MM-2.0 is a charge pump-based LED driver manufactured by National Semiconductor (NSC). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** Charge Pump LED Driver  
- **Output Current:** 20mA per channel (adjustable)  
- **Number of Outputs:** 2  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Package:** 10-pin MSOP (Mini Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The LM2798MM-2.0 is a dual-output, regulated charge pump designed to drive LEDs with constant current. It eliminates the need for external inductors, making it suitable for space-constrained applications. The device includes an internal current regulator for each output, ensuring uniform brightness across LEDs.

### **Features:**
- **No Inductor Required:** Charge pump topology simplifies design.  
- **Adjustable Output Current:** Set via external resistors.  
- **Low Dropout Operation:** Maintains regulation even with low input voltage.  
- **Automatic Soft Start:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **PWM Dimming Support:** Allows brightness control.  

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