Description and Introduction

5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers The MAX771MJA is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage Range:** Adjustable from 2.7V to 16.5V (fixed 5V or 12V options available)  
- **Output Current:** Up to 1A (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade, JA package)  
- **Package:** 8-Pin CERDIP (J)  

### **Descriptions:**  
- The MAX771MJA is a monolithic, current-mode PWM boost converter optimized for high-efficiency power conversion.  
- It includes an internal N-channel MOSFET switch for reduced external component count.  
- Designed for battery-powered applications, it provides stable output voltage even with varying input supply levels.  

### **Features:**  
- **Low Quiescent Current:** 110µA (typical)  
- **Internal Current Limiting:** Protects against overloads.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Wide Input Voltage Range:** Suitable for battery-powered systems.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

This information is based solely on the manufacturer's datasheet and technical documentation.
