Description and Introduction

Low Noise Regulated Switched Capacitor Voltage Inverter The LM2687MMX is a switching regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 3V to 5.5V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Switching Frequency:** 1.6 MHz (typical)  
- **Output Current:** Up to 600 mA  
- **Efficiency:** Up to 90%  
- **Package:** 10-pin MSOP (MMX)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:**  
  - Internal soft-start  
  - Low dropout operation  
  - Power-saving shutdown mode  
  - Over-temperature protection  

### **Descriptions:**  
The LM2687MMX is a step-up (boost) DC-DC converter designed for low-power applications. It integrates a power switch, oscillator, and control circuitry to efficiently boost input voltages to higher levels.  

### **Features:**  
- Fixed-frequency PWM operation  
- Low quiescent current (typically 1.1 mA)  
- Adjustable output voltage  
- Small footprint due to high switching frequency  
- Suitable for battery-powered applications  

This information is based on the official datasheet from National Semiconductor (NS).
