Description and Introduction

Low-Cost Multiple-Output Power Supply for LCD Monitors/TVs The **MAX8728ETJ+T** 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+T  
- **Package:** 32-TQFN (5x5)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4V to 28V  
- **Output Voltage Range:** Adjustable  
- **Number of Outputs:** Dual (Buck + Boost)  
- **Switching Frequency:** Adjustable (up to 1MHz)  
- **Features:** Synchronous rectification, soft-start, overcurrent/thermal protection  

### **Descriptions:**  
The **MAX8728ETJ+T** is a **dual-output power-supply controller** designed for applications requiring high efficiency and flexible power management. It integrates a **step-down (buck) regulator** and a **step-up (boost) regulator**, making it suitable for systems with multiple voltage rails.  

### **Features:**  
1. **Dual Power Conversion:**  
   - **Buck Regulator:** Converts high input voltage to a lower output voltage.  
   - **Boost Regulator:** Steps up input voltage to a higher output voltage.  
2. **Wide Input Voltage Range (4V to 28V):** Supports various power sources.  
3. **Adjustable Switching Frequency (up to 1MHz):** Allows optimization for efficiency or component size.  
4. **Synchronous Rectification:** Improves efficiency by reducing power loss.  
5. **Protection Features:**  
   - Overcurrent protection (OCP)  
   - Thermal shutdown  
   - Soft-start to limit inrush current  
6. **Compact 32-TQFN Package:** Space-saving design for portable and embedded applications.  

This IC is commonly used in **industrial, automotive, and battery-powered systems** where efficient power conversion is required.
