Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ DC-DC Inverters The MAX765CSA 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  
- **Part Number:** MAX765CSA  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable (up to 16.5V) or Fixed (5V, 12V, 15V)  
- **Output Current:** Up to 300mA (for 5V output)  
- **Switching Frequency:** 100kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
The MAX765CSA is a high-efficiency, step-up DC-DC converter designed for low-power applications. It integrates a power MOSFET switch, allowing it to generate higher output voltages from a lower input supply. The device is suitable for battery-powered systems, portable instruments, and other applications requiring regulated power conversion.  

### **Features:**  
- **Adjustable or Fixed Output Voltage** (factory-set options available)  
- **Low Quiescent Current** (typically 110µA)  
- **Internal Power MOSFET Switch** (eliminates the need for an external transistor)  
- **Low Battery Detection Comparator** (for monitoring input voltage)  
- **Short-Circuit Protection** (improves system reliability)  
- **Compact SOIC Package** (suitable for space-constrained designs)  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official MAX765CSA datasheet.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LT1109CS8-5 --: Pin-compatible inverting switching regulator in an 8-pin SOIC package with similar input voltage range and output current capability.
  • MC34063ACD --: Widely available general-purpose DC-DC converter IC that can be configured for inverting operation, offering a low-cost functional substitute.
  • LM2575-5.0 --: Simple switcher regulator with integrated switch, suitable as a functional replacement where a slightly different topology and external component set is acceptable.
  • LT1109CS8 --: Pin-compatible inverting DC-DC converter in SO-8 with similar input voltage range and output current, widely used as a MAX765 substitute.
  • LM2596S-ADJ --: Adjustable buck regulator that can be wired in an inverting configuration for negative outputs, with higher current capability and broad availability.
  • LTC1144CS8 --: Switched-capacitor inverting converter in SOIC-8 providing a negative supply from a positive input, usable as an alternative where the MAX765's inverting function is required.
  • LM2662M --: Switched-capacitor voltage inverter in an SOIC package providing negative output, usable in similar low-current inverting supply applications.
  • LM2575INV --: Simple switcher inverting regulator offering similar functionality and current rating, suitable for drop-in replacement with minor layout changes.
