Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low IQ Inverting DC-to-DC Controllers The MAX774ESA+ is a voltage regulator manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM (Maxim Integrated)  

### **Specifications:**  
- **Type:** Negative Output, Step-Up DC-DC Converter  
- **Input Voltage Range:** 1.5V to 16.5V  
- **Output Voltage:** Adjustable (negative output)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC (ESA)  

### **Descriptions:**  
The MAX774ESA+ is a high-efficiency, low-power, step-up DC-DC converter that generates a negative output voltage from a positive input. It is designed for applications requiring a regulated negative voltage supply with minimal external components.  

### **Features:**  
- Low quiescent current (120µA typical)  
- Adjustable output voltage  
- Internal power MOSFET switch  
- Short-circuit protection  
- Thermal shutdown protection  
- Small footprint (SOIC-8 package)  

This information is based solely on the manufacturer's specifications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LT1170CT --: High-efficiency inverting switching regulator with comparable input voltage range and current capability, widely used as a MAX774 substitute in negative-output converter designs.
  • MC34063A --: Versatile inverting/step-down/step-up DC-DC controller that can be configured for negative output, low cost and widely available as a functional alternative.
  • LM2576-ADJ --: Adjustable buck regulator that can be wired in inverting configuration, offering similar voltage/current ratings and broad availability for replacement designs.
