Description and Introduction

Adjustable step-up current-mode DC-DC converter The MAX752CPA is a voltage regulator manufactured by Maxim Integrated. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX752CPA  
- **Package:** 8-Pin PDIP (Plastic Dual Inline Package)  
- **Output Voltage:** Adjustable (5V to 15V)  
- **Output Current:** Up to 200mA  
- **Input Voltage Range:** 4.5V to 15V  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Regulation Type:** Step-Up (Boost) DC-DC Converter  

### **Descriptions:**  
The MAX752CPA is a monolithic, CMOS, step-up DC-DC switching regulator designed to provide a regulated output voltage higher than the input supply. It is optimized for low-power applications and includes an internal power switch, oscillator, and control circuitry.  

### **Features:**  
- Adjustable output voltage (5V to 15V)  
- Low supply current (100µA typical)  
- Internal power MOSFET switch  
- No external diode required (internal synchronous rectifier)  
- Low shutdown current (1µA typical)  
- Short-circuit and over-temperature protection  
- Small external component count

Application Scenarios & Design Considerations

Adjustable step-up current-mode DC-DC converter

Alternative Part Number

  • LT1073CN8 --: Pin-compatible step-up/step-down switching regulator in DIP-8 with similar input voltage range and current capability, widely used as a MAX752 substitute.
  • MC34063ACP --: Industry-standard DIP-8 DC-DC switching regulator covering boost, buck and inverting topologies; very common and cost-effective replacement for MAX752 designs.
  • LM2575T-ADJ --: Adjustable step-down switching regulator in TO-220 with integrated switch, suitable when the MAX752 circuit is used in a buck configuration and higher current is needed.
  • LM2577N-ADJ --: Adjustable step-up switching regulator in DIP package with comparable switching frequency and output current, suitable as an alternative boost converter solution.
