Description and Introduction

Advanced Li+ Battery-Pack Protectors The MAX1924XEEE is a DC-DC converter from Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Step-Down (Buck) DC-DC Converter  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Exposed Pad)  

### **Descriptions:**  
The MAX1924XEEE is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated low-voltage supply from a higher input voltage. It integrates a synchronous rectifier for improved efficiency and operates at a fixed switching frequency of 500kHz.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 28V)** – Suitable for various power sources.  
- **Adjustable Output Voltage (1.25V to 5.5V)** – Configurable via external resistors.  
- **High Efficiency (Up to 95%)** – Reduces power dissipation.  
- **500kHz Switching Frequency** – Enables small external components.  
- **Synchronous Rectification** – Improves efficiency compared to diode-based designs.  
- **Low Quiescent Current (100µA typ.)** – Enhances battery life in portable applications.  
- **Thermal Shutdown & Short-Circuit Protection** – Ensures safe operation.  
- **16-QSOP Package with Exposed Pad** – Improves thermal performance.  

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