Description and Introduction

60mA, SOT23 Inverting Charge Pump with Shutdown The **MAX1697TEUT+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 40V  
- **Output Voltage Range:** Adjustable from 1.25V to 10V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-Pin SOT23 (TDFN)  

### **Descriptions:**  
- The MAX1697TEUT+T is a **synchronous buck (step-down) DC-DC converter** designed for high-voltage applications.  
- It integrates both high-side and low-side MOSFETs for improved efficiency.  
- Features **current-mode control** for stable operation across varying loads.  
- Includes **soft-start** to limit inrush current during startup.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 40V)** – Suitable for automotive and industrial applications.  
- **High Efficiency (Up to 95%)** – Reduces power dissipation.  
- **Internal Synchronous Rectification** – Eliminates the need for an external Schottky diode.  
- **Adjustable Output Voltage (1.25V to 10V)** – Set via external resistors.  
- **Overcurrent and Thermal Protection** – Enhances reliability.  
- **Low Quiescent Current (40µA in Shutdown Mode)** – Improves power savings.  

This device is commonly used in **automotive, industrial, and telecom power supplies** where high efficiency and compact size are critical.
