Description and Introduction

Low-Cost Voltage-Mode PWM Step-Down Controllers The **MAX1967EUB+T** is a high-efficiency, step-down DC-DC converter manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 23V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable via external resistors)  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (3mm x 5mm)  
- **Regulation:** ±1% over line, load, and temperature  

### **Descriptions:**  
- The MAX1967EUB+T is a synchronous buck (step-down) DC-DC converter optimized for high efficiency and compact designs.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- Features include soft-start, overcurrent protection, and thermal shutdown for robust operation.  

### **Features:**  
- **High Efficiency:** Up to 95% with synchronous rectification.  
- **Wide Input Range:** Supports 4.5V to 23V input, suitable for various power sources.  
- **Adjustable Output:** Configurable from 0.8V to 5.5V via external resistors.  
- **Integrated MOSFETs:** Eliminates the need for external switches.  
- **Protection Features:** Overcurrent, thermal shutdown, and soft-start.  
- **Low Dropout Operation:** Maintains regulation even when the input voltage is close to the output.  
- **Compact Package:** 10-pin µMAX for space-constrained applications.  

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