Description and Introduction

125mA, Frequency-Selectable, Switched-Capacitor Voltage Converters The MAX1680ESA+ is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (MAIXM).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 26V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 100kHz  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX1680ESA+ is a synchronous-rectified PWM step-down DC-DC converter optimized for high efficiency and compact designs. It integrates a power MOSFET switch and synchronous rectifier, reducing external component count.  

### **Features:**  
- **Low Dropout Operation:** Allows high duty cycles for extended battery life.  
- **Internal Soft-Start:** Reduces inrush current.  
- **Current-Limiting Protection:** Safeguards against overloads.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Synchronous Rectification:** Improves efficiency compared to diode-based designs.
