Description and Introduction

-5V/-12V/-15V or Adjustable, High-Efficiency, Low-IQ DC-DC Inverters The MAX764ESA+T is a step-down DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 3V to 16V  
- **Output Voltage:** Adjustable (3.3V, 5V, or 12V preset, or externally adjustable)  
- **Output Current:** Up to 250mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX764ESA+T is a high-efficiency, low-power, step-down DC-DC converter designed for battery-powered and portable applications. It features a current-limited PFM control scheme for improved efficiency at light loads.  

### **Features:**  
- **Low Quiescent Current:** 120µA (typical)  
- **Low Dropout Operation:** Allows input voltages close to the output  
- **Internal Power Switch:** Simplifies design  
- **Battery Low Indicator:** Optional feature for monitoring input voltage  
- **Soft-Start Capability:** Reduces inrush current  
- **Short-Circuit Protection:** Enhances reliability  

This device is commonly used in portable electronics, battery-powered systems, and embedded applications requiring efficient power conversion.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LT1073CS8#PBF --: Pin-compatible inverting DC-DC converter in SO-8 with similar input range and current capability; well-established second source.
  • MC34063ACD-TR --: Widely available general-purpose inverting/switching regulator in SO-8, low cost and easy to source as a functional substitute.
  • LM2596S-ADJ/NOPB --: Adjustable buck/inverting regulator with higher current rating; usable as a drop-in functional alternative when board space allows.
