Description and Introduction

Negative output, inverting, current-mode PWM regulator. Converts +2.7V to +9V input to adjustable negative output. The MAX755ESA is a voltage regulator manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX755ESA  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Input Voltage Range:** 4V to 11.5V  
- **Output Voltage:** Adjustable (3.3V, 5V, or 12V preset, or externally adjustable)  
- **Output Current:** Up to 200mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 1.7mA (typical)  

### **Descriptions:**  
The MAX755ESA is a step-up (boost) DC-DC switching regulator that provides a regulated output voltage from an unregulated input supply. It is designed for low-power applications requiring efficient voltage conversion. The device includes an internal power switch, simplifying design and reducing external component count.  

### **Features:**  
- **Adjustable or Fixed Output Voltage** (3.3V, 5V, or 12V)  
- **Low Quiescent Current** (1.7mA typical)  
- **Internal Power MOSFET Switch**  
- **High Efficiency (Up to 85%)**  
- **Low Battery Detection Comparator**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Protection**  
- **Small Footprint (8-SOIC Package)**  

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

Application Scenarios & Design Considerations

Negative output, inverting, current-mode PWM regulator. Converts +2.7V to +9V input to adjustable negative output.

Alternative Part Number

  • LT1073CS8 --: Inverting DC-DC converter in an 8-pin SOIC package with comparable input voltage range and switching current, suitable as a functional replacement for the MAX755ESA.
  • MC34063ACD --: Widely available general-purpose inverting/switching regulator in SOIC-8 that can be configured for negative output, offering a low-cost drop-in style alternative.
  • LM2596S-ADJ --: Adjustable buck regulator in a similar SOIC package that can be adapted for negative rail generation, with high availability and robust current capability.
