Description and Introduction

4A 500 kHz / 1 MHz Synchronous SIMPLE SWITCHER? Buck Regulator 16-HTSSOP -40 to 85 The LM2854MH-500/NOPB is a step-down DC-DC converter manufactured by Texas Instruments (NS refers to National Semiconductor, which was acquired by TI).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 40V  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 150kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (PowerPAD™)  

### **Descriptions:**  
- A monolithic buck regulator designed for step-down voltage conversion.  
- Features internal power MOSFETs for compact design.  
- Includes thermal shutdown and current limiting for protection.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4V to 40V input.  
- **Fixed 5V Output:** No external feedback resistors needed.  
- **Low Quiescent Current:** Typically 2.5mA.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Current Limiting:** Protects against overloads.  

This device is suitable for industrial, automotive, and general-purpose power supply applications.
