Description and Introduction

Interleaved High-Efficiency, Dual Power-Supply Controllers for Notebook Computers The MAX8757ETI+ 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 information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Category:** Power Management IC (PMIC)  
- **Package:** 28-TQFN (5x5mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 26V  
- **Output Voltage Range:** Adjustable (depends on configuration)  
- **Switching Frequency:** Up to 1MHz  
- **Number of Outputs:** Dual (Buck + Boost)  
- **Efficiency:** Up to 95%  

### **Descriptions:**  
The **MAX8757ETI+** is a **dual-output, high-efficiency DC-DC converter** designed for applications requiring both step-down (buck) and step-up (boost) voltage regulation. It is optimized for **battery-powered systems, portable devices, and industrial applications** where high efficiency and compact size are critical.  

### **Features:**  
- **Dual Outputs:**  
  - **Buck Regulator:** Provides step-down conversion.  
  - **Boost Regulator:** Provides step-up conversion.  
- **Wide Input Voltage Range (4.5V to 26V):** Supports various power sources.  
- **High Efficiency (up to 95%):** Reduces power loss and heat dissipation.  
- **Adjustable Output Voltage:** Configurable via external resistors.  
- **Synchronous Rectification:** Improves efficiency.  
- **Integrated Power MOSFETs:** Reduces external component count.  
- **Soft-Start Function:** Prevents inrush current.  
- **Overcurrent & Overtemperature Protection:** Enhances reliability.  
- **1MHz Switching Frequency:** Allows for smaller external components.  

This IC is commonly used in **automotive, industrial, and portable electronics** where efficient power conversion is required.
