Description and Introduction

Stand-Alone, Switch-Mode Li Battery Charger with Internal 14V Switch The MAX1757EAI 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:  

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 1.25V to 10V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  
- **Protection Features:** Overcurrent, thermal shutdown, and undervoltage lockout (UVLO)  

### **Descriptions:**  
- The MAX1757EAI is a synchronous buck (step-down) DC-DC converter designed for high-efficiency power conversion.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- Suitable for industrial, automotive, and telecom applications requiring wide input voltage ranges.  

### **Features:**  
- **Wide Input Voltage Range (4V to 36V)** – Supports various power sources.  
- **High Efficiency (Up to 95%)** – Minimizes power loss.  
- **Adjustable Output Voltage (1.25V to 10V)** – Flexible for different loads.  
- **Integrated Power MOSFETs** – Simplifies design and reduces board space.  
- **300kHz Fixed Switching Frequency** – Balances efficiency and component size.  
- **Protection Circuits** – Includes overcurrent, thermal shutdown, and UVLO for reliability.  
- **Soft-Start Function** – Reduces inrush current during startup.  

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