Description and Introduction

Wide Brightness Range CCFL Backlight Controllers The MAX1839EEP is a step-down DC-DC converter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-QSOP (Exposed Pad)  

### **Descriptions:**  
The MAX1839EEP is a high-efficiency, step-down DC-DC converter designed for portable applications. It integrates a synchronous rectifier to minimize external component count and improve efficiency. The device operates at a fixed 1.2MHz switching frequency, allowing the use of small inductors and capacitors.  

### **Features:**  
- **High Efficiency:** Up to 95% efficiency with synchronous rectification.  
- **Low Dropout Operation:** Allows operation at 100% duty cycle for extended battery life.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Power-On Reset (POR):** Ensures proper startup under all conditions.  
- **Short-Circuit Protection:** Includes thermal shutdown for added safety.  
- **Low Quiescent Current:** 30µA (typical) in shutdown mode.  
- **Adjustable Output Voltage:** Set via external resistors.  

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