Description and Introduction

Low-Noise, 5.5V Input, PWM Step-Down Regulator The MAX1692EUB-T is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 1A  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (3mm x 5mm)  

### **Descriptions:**  
- The MAX1692EUB-T is a synchronous buck converter designed for high efficiency and compact size.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- Features include soft-start, overcurrent protection, and thermal shutdown for reliable operation.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Adjustable Output Voltage:** Set via external resistor divider.  
- **Low Quiescent Current:** 40µA (typical) in shutdown mode.  
- **Internal Compensation:** Simplifies design and reduces external components.  
- **Overcurrent and Thermal Protection:** Enhances system reliability.  
- **Soft-Start Function:** Prevents inrush current during startup.  

This device is commonly used in automotive, industrial, and general-purpose power supply applications.
