Description and Introduction

40V Wide Vin Low-Side N-Channel Controller for Switching Regulators 8-VSSOP -40 to 125 The **LM3488MMX/NOPB** is a switching regulator manufactured by **National Semiconductor (NS)**.  

### **Key Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Output Current:** Up to 5A (with external components)  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin VSSOP (MSOP)  

### **Descriptions and Features:**  
- **Buck/Boost/Flyback Capability:** Can be configured for step-down (buck), step-up (boost), or flyback topologies.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Current Mode Control:** Improves transient response and stability.  
- **Integrated N-Channel MOSFET Driver:** Reduces external component count.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  

This regulator is commonly used in **industrial, automotive, and power supply applications** due to its wide input range and flexibility.
