Description and Introduction

Adjustable / Step-Down / Current-Mode PWM Regulators The MAX758ACPA is a step-up (boost) switching regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX758ACPA  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  
- **Input Voltage Range:** 4V to 16V  
- **Output Voltage:** Adjustable from 5V to 12V (set by external resistors)  
- **Output Current:** Up to 750mA (depending on input/output conditions)  
- **Switching Frequency:** 170kHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 1.7mA (typical)  

### **Descriptions:**  
The MAX758ACPA is a monolithic, current-mode, step-up DC-DC switching regulator designed for battery-powered applications. It provides a regulated output voltage higher than the input voltage, making it suitable for systems requiring a boosted supply rail. The device includes an internal N-channel power MOSFET switch, reducing the need for external components.  

### **Features:**  
- Adjustable output voltage (5V to 12V)  
- Internal 1.5A power switch  
- Low battery detector with adjustable threshold  
- Soft-start capability to limit inrush current  
- Overcurrent protection  
- Thermal shutdown protection  
- Minimal external components required  

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

Application Scenarios & Design Considerations

Adjustable / Step-Down / Current-Mode PWM Regulators

Alternative Part Number

  • LT1073CN8 --: Adjustable step-up/step-down switching regulator in 8-pin DIP with comparable input range and current capability, a common drop-in style replacement for MAX758 designs.
  • MC34063ACP --: Widely available general-purpose DC-DC switching regulator in DIP-8 that can be configured for boost/buck/inverting topologies similar to the MAX758, with broad second-source availability.
  • LM2575T-ADJ --: Adjustable step-down switching regulator in TO-220 that covers similar voltage/current needs and is a robust, well-stocked alternative when layout can accommodate a different package.
  • LM2594N-ADJ --: Adjustable buck regulator in 8-pin DIP with similar switching topology and current rating, suitable when layout and feedback network are adapted.
