Description and Introduction

4A 500 kHz / 1 MHz Synchronous SIMPLE SWITCHER? Buck Regulator 16-HTSSOP -40 to 85 The LM2854MH-1000 is a step-down DC-DC converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 40V  
- **Output Voltage:** 1.0V (fixed)  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 500 kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Pin HTSSOP (Exposed Pad)  

### **Descriptions:**  
The LM2854MH-1000 is a high-efficiency, step-down (buck) switching regulator designed for applications requiring a stable 1.0V output from a wide input voltage range. It integrates a power MOSFET and control circuitry, reducing external component count.  

### **Features:**  
- **Wide Input Voltage Range (4V to 40V)**  
- **Fixed 1.0V Output Voltage**  
- **High Efficiency (Up to 90%)**  
- **Internal Power MOSFET**  
- **500 kHz Switching Frequency**  
- **Thermal Shutdown Protection**  
- **Overcurrent Protection**  
- **Low Quiescent Current in Shutdown Mode**  

This device is commonly used in industrial, automotive, and battery-powered applications requiring a regulated low-voltage supply.
