Description and Introduction

Low-Cost Multiple-Output Power Supply for LCD Monitors/TVs The MAX8728ETJ+ 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  
- **Part Number:** MAX8728ETJ+  
- **Package:** 32-TQFN (5x5)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable  
- **Number of Outputs:** Dual (Buck + Boost or Buck + LDO configurations possible)  
- **Switching Frequency:** Up to 1MHz  

### **Descriptions:**  
The MAX8728ETJ+ is a **high-efficiency, dual-output power-supply controller** designed for **battery-powered and portable applications**. It integrates a **step-down (buck) regulator** and a **boost or LDO controller**, providing flexibility in power management. It supports **low-power modes** for improved efficiency in standby operation.  

### **Features:**  
- **Dual-output power management** (Buck + Boost or Buck + LDO)  
- **Wide input voltage range** (4.5V to 24V)  
- **High efficiency** with synchronous rectification  
- **Adjustable switching frequency** (up to 1MHz)  
- **Low-power shutdown mode**  
- **Overvoltage and thermal protection**  
- **Small footprint** (32-pin TQFN package)  

This IC is commonly used in **laptops, tablets, portable devices, and industrial applications** requiring efficient power conversion.
