Description and Introduction

400mA Sub-miniature, Programmable, Step-Down DC-DC Converter for Ultra Low-Voltage Circuits The LM2612BBP is a switching regulator manufactured by National Semiconductor (NSC). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 14V  
- **Output Voltage Range:** Adjustable from 1.24V to 13.5V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 1.4MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**
- The LM2612BBP is a high-efficiency, step-down (buck) DC-DC converter.  
- It is designed for applications requiring high current output with minimal external components.  
- The device operates in a fixed-frequency PWM mode for stable performance.  

### **Features:**
- **Wide Input Voltage Range:** Supports 2.7V to 14V input.  
- **High Efficiency:** Up to 90% efficiency due to low dropout operation.  
- **Adjustable Output:** Output can be set via external resistors.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Low Quiescent Current:** Enhances efficiency in light-load conditions.  

This information is based solely on the manufacturer's datasheet for the LM2612BBP.
