Description and Introduction

Step-Up DC-DC Converters with Precise, Adaptive Current Limit for GSM The MAX1688EUE+ is a high-efficiency, step-down DC-DC converter from 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 37V  
- **Output Current:** Up to 350mA  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-TSSOP (Exposed Pad)  

### **Descriptions:**  
The MAX1688EUE+ is a step-down (buck) DC-DC converter designed for high-voltage applications. It integrates a power MOSFET switch and provides a regulated output with minimal external components. It is suitable for industrial, automotive, and general-purpose power supply applications.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 40V)** – Supports high-voltage inputs.  
- **Adjustable Output Voltage (1.25V to 37V)** – Set via external resistors.  
- **Internal Power MOSFET Switch** – Simplifies design and reduces external components.  
- **Low Quiescent Current (100µA typical)** – Improves efficiency at light loads.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Short-Circuit Protection** – Enhances reliability.  
- **Fixed 100kHz Switching Frequency** – Reduces EMI interference.  

This device is ideal for applications requiring efficient power conversion from higher input voltages to lower output voltages.
