Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ DC-DC Inverters The MAX764CPA 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 Integrated (now Analog Devices)  
- **Part Number:** MAX764CPA  
- **Type:** Step-Down (Buck) DC-DC Converter  
- **Input Voltage Range:** 3V to 16V  
- **Output Voltage:** Adjustable (1.25V to 15V) or Fixed (5V, 12V, 15V)  
- **Output Current:** Up to 250mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **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 MAX764CPA is a high-efficiency, step-down DC-DC converter designed for low-power applications. It features a fixed or adjustable output voltage and operates with a high switching frequency, allowing the use of small external components. The device is suitable for battery-powered systems, portable electronics, and other applications requiring efficient power conversion.  

### **Features:**  
- **Wide Input Voltage Range (3V to 16V)** – Supports various power sources.  
- **Adjustable or Fixed Output Voltage** – Configurable for different requirements.  
- **High Efficiency (Up to 90%)** – Minimizes power loss.  
- **Low Quiescent Current (110µA typ.)** – Extends battery life.  
- **300kHz Switching Frequency** – Reduces inductor and capacitor size.  
- **Short-Circuit Protection** – Enhances reliability.  
- **Thermal Shutdown** – Prevents overheating.  
- **Small External Component Count** – Simplifies PCB design.  

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

Application Scenarios & Design Considerations

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ DC-DC Inverters

Alternative Part Number

  • LT1073CN8 --: Inverting DC-DC converter with similar input voltage range and output current, pin-compatible DIP-8 package, widely used as a MAX764 substitute.
  • MC34063ACN --: Versatile inverting switching regulator in DIP-8, supports similar input/output voltage ranges and is a common low-cost alternative for MAX764 designs.
  • LM2575IN-ADJ --: Adjustable step-down/inverting regulator in DIP-8 with comparable current capability, usable as a functional replacement with minor circuit adjustments.
  • MC34063ACP --: Versatile inverting/switching regulator in 8-pin DIP that can be configured for the same negative-output application, very common and low cost.
  • MC34063AP --: Versatile inverting switching regulator in DIP-8 that can be configured for the same negative output topology at comparable currents.
  • LM2574N-ADJ --: Adjustable buck-boost capable regulator in DIP-8 package, suitable for negative rail generation with external components.
