Description and Introduction

Low-Cost CCFL Backlight Controller The **MAX8722CEEG+** is a power management IC (PMIC) manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
- **Maxim Integrated** (now Analog Devices)  

### **Specifications:**  
- **Package:** 16-QSOP (0.154", 3.90mm Width)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Mounting Type:** Surface Mount  
- **Function:** Step-Up (Boost) DC-DC Controller  
- **Output Type:** Adjustable  
- **Number of Outputs:** 1  
- **Topology:** Boost (Step-Up)  
- **Voltage - Supply (Vcc/Vdd):** 2.6V to 5.5V  
- **Frequency - Switching:** Up to 1MHz  
- **Duty Cycle (Max):** 90%  
- **Synchronous Rectifier:** No  

### **Descriptions:**  
- The **MAX8722CEEG+** is a high-efficiency, step-up DC-DC controller designed for driving N-channel MOSFETs in boost (step-up) applications.  
- It is optimized for low-voltage input (as low as 2.6V) and provides an adjustable output voltage.  
- Suitable for battery-powered systems, portable devices, and applications requiring regulated high-voltage outputs from a low-voltage source.  

### **Features:**  
- **Wide Input Voltage Range:** 2.6V to 5.5V  
- **Adjustable Output Voltage** (externally set via resistors)  
- **High Switching Frequency (up to 1MHz)** allows for smaller external components.  
- **Low Quiescent Current:** Improves efficiency in battery-operated applications.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Current-Limit Protection:** Safeguards against overcurrent conditions.  

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