Description and Introduction

SMBus Level 2 Battery Charger with Remote Sense The MAX8731ETI+ is a power management IC (PMIC) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX8731ETI+  
- **Package:** 28-pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable (depends on configuration)  
- **Switching Frequency:** Up to 1MHz  

### **Descriptions:**  
The MAX8731ETI+ is a **dual-output, step-down DC-DC controller** designed for high-efficiency power conversion in notebook computers and other portable devices. It integrates two synchronous buck controllers, providing regulated voltages for core and I/O power rails.  

### **Features:**  
- **Dual Synchronous Buck Controllers:** Supports two independent step-down converters.  
- **Adjustable Output Voltages:** Configurable via external resistors.  
- **High Efficiency:** Uses synchronous rectification for improved power conversion.  
- **Programmable Switching Frequency:** Up to 1MHz for optimized performance.  
- **Power-Good Outputs:** Monitors both regulator outputs for fault detection.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent and Thermal Protection:** Enhances system reliability.  

This IC is commonly used in **laptops, portable electronics, and embedded systems** requiring dual regulated power supplies.
