Description and Introduction

±1°C Fail-Safe Remote/Local Temperature Sensors with SMBus Interface The MAX6680MEE+ is a step-up DC-DC controller manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 28V  
- **Output Voltage Range:** Up to 28V (adjustable via external resistors)  
- **Switching Frequency:** Adjustable (100kHz to 500kHz)  
- **Maximum Output Current:** Dependent on external components  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Quad Flat Small Outline Package)  
- **Efficiency:** Up to 95% (depending on configuration)  
- **Duty Cycle:** Up to 94%  

### **Description:**  
The MAX6680MEE+ is a **PWM step-up (boost) DC-DC controller** designed for applications requiring high-efficiency power conversion. It features an integrated **N-channel MOSFET driver**, allowing flexibility in selecting external power MOSFETs. The device supports **low input voltage operation** (down to 1.8V) and is suitable for battery-powered systems, portable electronics, and industrial applications.  

### **Features:**  
- **Wide Input Voltage Range (1.8V–28V)**  
- **Adjustable Output Voltage** (up to 28V)  
- **External MOSFET Drive Capability** (for higher power designs)  
- **Programmable Soft-Start** (reduces inrush current)  
- **Low 100µA Shutdown Current**  
- **Overvoltage Protection (OVP)**  
- **Thermal Shutdown Protection**  
- **Adjustable Switching Frequency (100kHz–500kHz)**  
- **Synchronous Rectification Support** (improves efficiency)  

The MAX6680MEE+ is commonly used in **battery-powered devices, LED drivers, and industrial power supplies**. For detailed application circuits, refer to the official datasheet from **Analog Devices (formerly MAXIM Integrated)**.
