Description and Introduction

Adjustable step-up current-mode DC-DC converter The MAX752EWE is a step-up DC-DC switching regulator 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  
- **Part Number:** MAX752EWE  
- **Package:** 16-pin Wide SOIC (SO-16W)  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable from 5V to 12V (set via external resistor divider)  
- **Output Current:** Up to 200mA (depending on input/output conditions)  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:**  
  - Low quiescent current (120µA typical)  
  - Internal power MOSFET switch  
  - Soft-start capability  
  - Undervoltage lockout (UVLO)  
  - Current-limited operation  

### **Description:**  
The MAX752EWE is a step-up (boost) DC-DC converter designed to generate higher output voltages from low input voltages. It integrates a power MOSFET switch, reducing external component count. The device is suitable for battery-powered applications where efficient power conversion is required.  

### **Features:**  
- Adjustable output voltage (5V to 12V)  
- Low shutdown current (5µA max)  
- Internal current limiting  
- Thermal shutdown protection  
- Small external component count  
- Wide input voltage range (2V to 16.5V)  

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

Application Scenarios & Design Considerations

Adjustable step-up current-mode DC-DC converter

Alternative Part Number

  • LT1073CS8 --: Adjustable step-up/step-down switching regulator in an 8-pin SOIC package with comparable input voltage range and current capability, a common cross for MAX752 designs.
  • MC34063ACD --: Widely available general-purpose DC-DC switching regulator in SOIC-8 that can be configured for boost or buck operation, often used as a drop-in functional substitute for MAX752 circuits.
  • LM2575S-ADJ --: Adjustable step-down switching regulator in a similar surface-mount package with integrated switch, suitable when the MAX752 is used in a buck configuration and a simple, well-stocked alternative is needed.
  • LM2577S-ADJ --: Adjustable step-up switching regulator in a surface-mount package with similar boost conversion capability and current handling, suitable as a drop-in style alternative for many MAX752 applications.
  • LT1370CT7 --: High-efficiency step-up switching regulator with comparable input/output range and current capability; well-established alternative to the MAX752 boost converter.
  • MC34063A --: Widely available general-purpose DC-DC switching regulator that can be configured as a boost converter covering similar voltage and current requirements at lower cost.
  • LM2585T-ADJ --: Adjustable step-up switching regulator with integrated switch, suitable as a functional replacement for the MAX752 in boost applications.
