Description and Introduction

12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Converters The MAX761ESA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX761ESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable (up to ±16.5V) or fixed (12V, 15V)  
- **Switching Frequency:** 300kHz  
- **Output Current:** Up to 200mA (depending on configuration)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX761ESA is a step-up (boost) DC-DC switching regulator that efficiently converts a low input voltage to a higher output voltage. It is designed for battery-powered applications, portable devices, and other systems requiring regulated power from an unregulated source.  

### **Features:**  
- **Low Input Voltage Operation:** Works down to 2V, making it suitable for battery-powered applications.  
- **Adjustable or Fixed Output:** Can be configured for adjustable output or preset 12V/15V.  
- **High Efficiency:** Up to 90% conversion efficiency.  
- **Low Quiescent Current:** Typically 110µA, extending battery life.  
- **Internal Power Switch:** Simplifies external circuitry.  
- **Current-Limiting Protection:** Prevents damage from overload conditions.  
- **Small Footprint:** Available in an 8-pin SOIC package for space-constrained designs.  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Converters

Alternative Part Number

  • LT1372CS8 --: Boost switching regulator in an SO-8 package with comparable input voltage range and current capability, widely used as a MAX761 functional substitute.
  • MC34063A --: Versatile DC-DC switching regulator controller that can be configured for boost operation, very common and low-cost drop-in style alternative for simple boost designs.
  • LM2577S-ADJ --: Adjustable step-up switching regulator in a similar package with adequate switch current, suitable for boost converter applications replacing the MAX761.
  • MC34063ACD --: Widely available general-purpose DC-DC switching regulator in SOIC-8 that can be configured for boost or inverting topologies similar to the MAX761, with broad second-source availability.
