Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ DC-DC Inverters The MAX765CPA is a DC-DC switching regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX765CPA  
- **Type:** Step-Up (Boost) DC-DC Switching Regulator  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable (up to 16.5V) or fixed 5V, 12V, or 15V versions available  
- **Output Current:** Up to 300mA (for 5V output)  
- **Switching Frequency:** 100kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The MAX765CPA is a high-efficiency, step-up DC-DC switching regulator designed for battery-powered applications. It provides a stable output voltage from a low input voltage, making it suitable for portable electronics, data acquisition systems, and other power-sensitive designs.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 2V to 16.5V.  
- **Adjustable or Fixed Output Voltage:** Available in 5V, 12V, or 15V fixed versions or adjustable via external resistors.  
- **High Efficiency:** Up to 85% conversion efficiency.  
- **Low Quiescent Current:** Typically 110µA, improving battery life.  
- **Internal Power MOSFET:** Simplifies design by eliminating the need for an external switch.  
- **Short-Circuit Protection:** Includes built-in protection against output shorts.  
- **Low Battery Detector:** Optional feature for monitoring input voltage.  
- **Compact Package:** 8-Pin PDIP for easy integration.  

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

Application Scenarios & Design Considerations
