Description and Introduction

High-Efficiency / 26V Step-Up Converter for White LED Main and Subdisplay Backlighting The **MAX1582EBE+T** is a high-efficiency, step-up DC-DC converter manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 3V to 5.5V  
- **Output Current:** Up to **600mA** (at 3.3V output)  
- **Switching Frequency:** **1MHz** (fixed)  
- **Efficiency:** Up to **95%**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **16-pin QSOP** (Exposed Pad)  

### **Descriptions:**
- The **MAX1582EBE+T** is a **synchronous step-up DC-DC converter** optimized for portable applications.  
- It integrates **low RDS(ON) MOSFETs** for high efficiency and compact design.  
- Features **pulse-width modulation (PWM)** operation for stable output.  
- Includes **soft-start** to limit inrush current and **undervoltage lockout (UVLO)** for protection.  

### **Features:**
- **High Efficiency (up to 95%)**  
- **Low Quiescent Current (30µA in shutdown mode)**  
- **Adjustable Output Voltage** (via external resistors)  
- **Internal Synchronous Rectifier** (eliminates need for external diode)  
- **Overcurrent and Thermal Protection**  
- **Small Footprint (QSOP-16 package with exposed pad for thermal dissipation)**  

This device is commonly used in **battery-powered applications**, such as **smartphones, PDAs, and portable electronics**, where high efficiency and compact size are critical.
