Description and Introduction

5V/-12V/-15V or Adjustable / High-Efficiency / Low IQ DC-DC Inverters The MAX766CPA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** MAXIM (now Analog Devices)  
- **Part Number:** MAX766CPA  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Input Voltage Range:** 3V to 16V  
- **Output Voltage:** Adjustable (via external resistors) or fixed (-12V, -15V, or adjustable)  
- **Output Current:** Up to 250mA (for -12V output)  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX766CPA is a step-down/step-up (inverting) switching regulator designed to generate negative output voltages from a positive input. It is commonly used in applications requiring efficient power conversion with minimal external components.  

### **Features:**  
- **Inverting DC-DC Converter:** Converts positive input to negative output.  
- **Low Quiescent Current:** Typically 110µA.  
- **Internal Power MOSFET:** Eliminates the need for an external switch.  
- **Adjustable or Fixed Output:** Supports -12V, -15V, or user-configurable output.  
- **Current-Limiting Protection:** Prevents damage from overloads.  
- **Low Dropout Operation:** Maintains regulation even with small input-output differentials.  

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