Description and Introduction

-5V/Adjustable, Negative-Output,Inverting, Current-mode PWM Regulators The **MAX755CSA** is a voltage regulator manufactured by **Maxim Integrated (now part of Analog Devices)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Step-Up (Boost) DC-DC Switching Regulator  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage:** Adjustable (3.3V, 5V, or preset 12V)  
- **Output Current:** Up to **200mA** (for 5V output)  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to **90%**  
- **Operating Temperature Range:** **0°C to +70°C**  
- **Package:** **8-pin SOIC (CSA)**  

### **Descriptions:**  
The **MAX755CSA** is a **step-up DC-DC converter** designed for low-input voltage applications. It efficiently boosts input voltages as low as **0.7V** to higher regulated outputs (3.3V, 5V, or 12V). It is commonly used in battery-powered devices, portable electronics, and energy harvesting systems.  

### **Features:**  
- **Low Start-Up Voltage (0.7V)** – Operates from very low input voltages.  
- **Adjustable or Fixed Output** – Supports preset 3.3V, 5V, or 12V outputs, or can be adjusted via external resistors.  
- **High Efficiency (Up to 90%)** – Optimized for power-sensitive applications.  
- **Low Quiescent Current (50µA)** – Improves battery life.  
- **Internal Power MOSFET** – Simplifies design and reduces external components.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Current-Limiting Protection** – Safeguards against overload conditions.  

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

Application Scenarios & Design Considerations

-5V/Adjustable, Negative-Output,Inverting, Current-mode PWM Regulators

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 MAX755 inverting regulator.
  • MC34063ACD --: Widely available inverting/switching regulator in SOIC-8 that can be configured for negative output conversion, offering a low-cost drop-in style alternative with similar current capability.
  • LM2596S-ADJ --: Adjustable buck regulator that can be wired in an inverting configuration, providing higher current capability and broad availability as a substitute for the MAX755 in many designs.
  • LM2575-5.0 --: Simple switcher regulator in the same power range; usable as a functional replacement when the inverting topology is adapted.
