Description and Introduction

12V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controller The MAX1771CPA+ is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 16.5V  
- **Output Voltage Range:** Adjustable up to 28V  
- **Output Current:** Up to 2A (with external FET)  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 94%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Regulation Type:** PWM (Pulse-Width Modulation)  

### **Descriptions:**  
The MAX1771CPA+ is a high-efficiency, step-up DC-DC converter designed for applications requiring a regulated high-voltage output from a low-voltage input. It integrates a high-performance controller that drives an external N-channel MOSFET for power conversion. The device is commonly used in battery-powered systems, LCD bias supplies, and industrial applications.

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 1.8V to 16.5V.  
- **Adjustable Output Voltage:** Configurable up to 28V.  
- **High Efficiency:** Up to 94% efficiency with synchronous rectification.  
- **External FET Drive:** Allows flexibility in power handling.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Current Limiting:** Protects against overload conditions.  
- **Low Quiescent Current:** Enhances battery life in portable applications.
