Description and Introduction

12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Converters The MAX761CSA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 1V to 16.5V  
- **Output Voltage:** Adjustable (up to 16.5V) or fixed (5V or 12V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX761CSA is a low-power, step-up DC-DC converter designed for battery-powered applications. It features an internal N-channel MOSFET switch and requires minimal external components. The device can operate from input voltages as low as 1V, making it suitable for single-cell or dual-cell battery systems. The output voltage can be adjusted using external resistors or set to a fixed value (5V or 12V).  

### **Features:**
- **Wide Input Voltage Range:** 1V to 16.5V  
- **Adjustable or Fixed Output Voltage** (5V or 12V)  
- **Low Quiescent Current:** 110µA (typical)  
- **Internal Power MOSFET Switch**  
- **Low Battery Detector Comparator**  
- **Soft-Start Capability**  
- **Thermal Shutdown Protection**  
- **Small 8-Pin SOIC Package**

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LT1372CS8 --: Step-up switching regulator in the same class as the MAX761, with comparable input voltage range and current capability; a well-established pin-compatible-style alternative from a different series.
  • MC34063ACD --: Widely available general-purpose DC-DC converter IC that can be configured as a boost regulator similar to the MAX761; very common and cost-effective substitute.
  • LM2577S-ADJ --: Adjustable step-up voltage regulator with similar boost function and current handling, offering a different series and manufacturer as a functional replacement.
  • LT1073CS8 --: Pin-compatible boost switching regulator with similar input voltage range and current capability, widely used as a MAX761 substitute.
