Description and Introduction

Compact, Dual-Output Charge Pump The MAX865EUA-T is a DC-DC converter manufactured by Maxim Integrated. Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Power Management IC (PMIC) - DC-DC Converters  
- **Package:** 8-pin μMAX  
- **Output Type:** Adjustable  
- **Topology:** Step-Up (Boost)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable up to 5.5V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX865EUA-T is a high-efficiency, step-up DC-DC converter designed for low-input voltage applications. It integrates a synchronous rectifier to improve efficiency and reduce external component count. The device is suitable for battery-powered systems, portable electronics, and other applications requiring a regulated output from a low-voltage source.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V input  
- **Synchronous Rectification:** Improves efficiency and reduces power loss  
- **Adjustable Output Voltage:** Set via external resistors  
- **Low Quiescent Current:** 20μA (typical)  
- **Internal Soft-Start:** Prevents inrush current  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Compact Package:** Space-saving 8-pin μMAX

Application Scenarios & Design Considerations

Compact, Dual-Output Charge Pump

Alternative Part Number

  • LT1054CS8#PBF --: Pin-compatible charge-pump voltage converter in SO-8 with similar inverting/doubling function and wide input range, a well-established alternative to the MAX865.
  • ICL7660ACPA --: Classic charge-pump inverter offering comparable negative-supply generation; widely available and functionally similar, though package and pinout should be verified.
  • TC7660EOA --: Low-cost charge-pump voltage converter in SO-8 with similar inverting capability, suitable as a functional substitute when exact electrical limits are checked.
  • LT1372CS8#PBF --: Pin-compatible boost/inverting switching regulator in SO-8 with similar input voltage range and current capability, widely available and a common drop-in substitute.
  • MC34063ACD-TR --: Industry-standard general-purpose DC-DC converter IC in SO-8 that can be configured for boost or inverting topologies like the MAX865, with broad availability and low cost.
  • LM2577S-ADJ --: Adjustable boost/flyback switching regulator in a similar package class, offering comparable functionality for designs needing a higher-current alternative.
  • LT1373CS8 --: Pin-compatible boost/inverting switching regulator in an 8-pin SOIC package with similar input voltage range and switching frequency, widely used as a drop-in substitute for the MAX865.
  • MC34063ACD --: Industry-standard general-purpose DC-DC converter IC in SOIC-8 that can be configured for boost, buck, or inverting topologies, offering a low-cost and readily available alternative for MAX865 applications.
