Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-to-DC Controllers The MAX775CSA+ is a DC-DC converter manufactured by **MAXIM** (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2V to 16.5V  
- **Output Voltage:** Adjustable from -12V to -40V  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 85%  
- **Package:** 8-pin SOIC  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX775CSA+ is a **negative-output step-up DC-DC converter** designed for applications requiring a regulated negative voltage from a positive input. It integrates a power switch, oscillator, and control circuitry, minimizing external components.  

### **Features:**  
- **High Efficiency:** Up to 85%  
- **Low Quiescent Current:** 1.5mA (typical)  
- **Adjustable Output Voltage** via external resistors  
- **Internal Power MOSFET** (no external switch needed)  
- **Short-Circuit Protection**  
- **Soft-Start Function** to limit inrush current  

This device is commonly used in **LCD bias supplies, portable instruments, and industrial applications** where a negative voltage rail is required.  

(Note: Always refer to the official datasheet for detailed specifications and application notes.)
