Description and Introduction

High-Voltage, Low-Power Linear Regulators for Notebook Computers The MAX8719ETA+T is a step-down controller manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX8719ETA+T  
- **Package:** 8-TDFN (3x3mm)  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX8719ETA+T is a high-efficiency, synchronous step-down DC-DC controller designed for high-current applications. It supports an adjustable output voltage and switching frequency, making it suitable for powering CPUs, GPUs, and other high-performance processors. The device integrates MOSFET drivers and requires external N-channel MOSFETs for operation.  

### **Features:**  
- **Adjustable Output Voltage:** 0.8V to 5.5V via external resistors.  
- **Wide Input Range:** 4.5V to 28V input voltage support.  
- **Programmable Frequency:** 300kHz to 1MHz for optimization of efficiency and component size.  
- **High Efficiency:** Up to 95% with synchronous rectification.  
- **Current-Mode Control:** Provides fast transient response and stable operation.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Power-Good Output:** Monitors output voltage status.  
- **Overcurrent and Thermal Protection:** Enhances system reliability.
