Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-DC Controllers The MAX774CSA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:  

### **Manufacturer:** MAXIM (now Analog Devices)  
### **Part Number:** MAX774CSA  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage:** Adjustable (via external resistors) or fixed (-5V, -12V, -15V)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 100kHz  
- **Efficiency:** Up to 80%  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The MAX774CSA is a high-efficiency, inverting DC-DC converter that generates a negative output voltage from a positive input.  
- It is designed for low-power applications requiring a compact and efficient voltage conversion solution.  
- The device includes an internal power switch, simplifying external circuitry.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4V to 30V input.  
- **Adjustable or Fixed Output:** Configurable for -5V, -12V, -15V, or user-defined output.  
- **Low Quiescent Current:** Typically 1.7mA.  
- **Internal Power MOSFET:** Reduces external component count.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Compact Package:** 8-pin SOIC for space-constrained designs.  

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

Application Scenarios & Design Considerations

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-DC Controllers

Alternative Part Number

  • LT1073CS8 --: Inverting DC-DC converter in an 8-pin SOIC package with similar input voltage range and switching topology, widely used as a MAX774 substitute.
  • MC34063ACD --: Versatile inverting/switching regulator in SOIC-8 that can be configured for the same negative-output application, very common and low cost.
  • LM2596S-ADJ --: Adjustable buck regulator in SOIC-8 that can be wired for inverting output with comparable current capability, though switching frequency differs.
