Description and Introduction

Low-Noise / 5.5V-Input / PWM Step-Down Regulator The MAX1692EUB is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (3mm x 3mm)  

### **Descriptions:**
- The MAX1692EUB is a synchronous step-down DC-DC converter designed for high-efficiency power conversion in automotive, industrial, and general-purpose applications.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- The device features a fixed-frequency PWM control scheme for stable operation.  

### **Features:**
- **Wide Input Voltage Range (4.5V to 28V)** – Suitable for automotive and industrial applications.  
- **High Efficiency (Up to 95%)** – Minimizes power loss.  
- **Internal Synchronous Rectification** – Improves efficiency and eliminates the need for an external Schottky diode.  
- **Adjustable Output Voltage (0.8V to 5.5V)** – Set via external resistors.  
- **Overcurrent and Thermal Protection** – Enhances reliability.  
- **Low Quiescent Current (40µA in Shutdown Mode)** – Reduces power consumption when idle.  
- **Soft-Start Function** – Prevents inrush current at startup.  

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