Description and Introduction

White LED 1x/1.5x Charge Pump for Main and Sub-Displays The MAX1575ETE+T is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.6V to 5.5V  
- **Output Voltage:** Adjustable from 3.3V to 5.5V (fixed 3.3V or 5.0V versions available)  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz  
- **Efficiency:** Up to 92%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin TQFN (5mm x 5mm)  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX1575ETE+T is designed for applications requiring a regulated voltage higher than the input supply, such as powering white LEDs or other low-voltage systems. It integrates a high-efficiency boost converter with synchronous rectification, minimizing external components.  

### **Features:**  
- **High Efficiency:** Up to 92% with synchronous rectification.  
- **Low Quiescent Current:** 0.5mA typical.  
- **PWM/PFM Mode Operation:** Optimizes efficiency across load conditions.  
- **Soft-Start:** Reduces inrush current.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Overcurrent Protection:** Safeguards the circuit.  
- **Small Footprint:** 16-pin TQFN package saves board space.  

This device is commonly used in portable electronics, LED drivers, and battery-powered applications.
