Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-DC Controllers The MAX774ESA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** DC-DC Converter (Inverting)  
- **Input Voltage Range:** 4.5V to 20V  
- **Output Voltage Range:** Adjustable (negative output)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 85%  
- **Package:** 8-pin SOIC (ESA)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX774ESA is a high-efficiency, inverting DC-DC converter designed to generate a negative output voltage from a positive input. It is commonly used in applications requiring a negative supply rail, such as op-amp biasing, data acquisition systems, and portable instruments.  

### **Features:**  
- **Low Quiescent Current:** 120µA (typical)  
- **Adjustable Output Voltage:** Set via external resistors  
- **Internal Power MOSFET:** Simplifies circuit design  
- **High Efficiency:** Up to 85%  
- **Short-Circuit Protection:** Improves reliability  
- **Low Dropout Operation:** Maintains regulation with minimal headroom  

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