Description and Introduction

Step-Down Controllers with Synchronous Rectifier for CPU Power The MAX797EPE is a step-down controller manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Step-Down (Buck) PWM Controller  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** 200kHz (fixed)  
- **Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 96%  
- **Package:** 16-pin Plastic DIP (PDIP)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX797EPE is a high-efficiency, step-down DC-DC controller designed for high-current applications. It operates in a fixed-frequency PWM mode and supports synchronous rectification for improved efficiency. It includes features such as soft-start, overcurrent protection, and undervoltage lockout (UVLO).  

### **Features:**  
- **Synchronous Rectification:** Enhances efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection:** Safeguards against excessive load currents.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage limits.  
- **Fixed 200kHz Switching Frequency:** Simplifies noise filtering.  
- **Wide Input Voltage Range:** Suitable for various power supply applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
