Description and Introduction

5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers The MAX772ESA is a DC-DC converter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** DC-DC Converter (Boost, Step-Up)  
- **Input Voltage Range:** 1.2V to 16.5V  
- **Output Voltage Range:** Adjustable (up to 28V)  
- **Output Current:** Up to 300mA (depends on input/output conditions)  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (MAX772ESA)  
- **Shutdown Current:** 1µA (typical)  

### **Descriptions:**  
The MAX772ESA is a high-efficiency, low-power step-up DC-DC converter designed for battery-powered applications. It can generate a higher output voltage from a low input voltage, making it suitable for systems requiring voltage conversion from single or multiple battery cells.  

### **Features:**  
- **Low Input Voltage Operation:** Works down to 1.2V.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Low Quiescent Current:** 120µA (typical).  
- **Internal Power MOSFET:** Simplifies external circuitry.  
- **Soft-Start Capability:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  

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

Application Scenarios & Design Considerations

5V/12V/15V or Adjustable, High-Efficiency, Low IQ, Step-Up DC-DC Controllers

Alternative Part Number

  • LT1302CS8 --: Low-voltage boost converter in an 8-pin SOIC package with comparable input range and switching function, widely used as a MAX772 substitute.
  • MC34063ACD --: Versatile DC-DC switching regulator in SOIC-8 that can be configured for boost operation, a common low-cost functional replacement.
  • TPS61020DRB --: Boost converter with integrated switch in a small package, offering similar step-up regulation for battery-powered designs.
  • LT1107CS8 --: Pin-compatible boost converter in the same 8-pin SOIC package with comparable input voltage and switching current ratings, widely available and well documented.
  • LM2700MT-ADJ --: Adjustable boost converter with similar current capability and SOIC/TSSOP footprint, suitable when layout flexibility allows a small package change.
