Description and Introduction

White LED 1x/1.5x Charge Pump for Main and Sub-Displays The MAX1575ETE+ is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Category:** Power Management (PMIC)  
- **Type:** DC-DC Switching Regulator  
- **Topology:** Step-Up (Boost)  
- **Input Voltage Range:** 2.6V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 28V)  
- **Output Current:** Up to 120mA (at 5V input, 15V output)  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 87%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-TQFN (3x3mm)  
- **Features:** Overcurrent protection, thermal shutdown, soft-start  

### **Descriptions:**  
The MAX1575ETE+ is a compact, high-efficiency boost converter designed for applications requiring a regulated high voltage from a low-voltage input, such as OLED displays, bias supplies, and portable devices. It integrates a power switch and offers a fixed-frequency PWM control scheme for stable performance.  

### **Features:**  
- **Wide Input Range:** Supports 2.6V to 5.5V input.  
- **Adjustable Output:** Configurable up to 28V via external resistors.  
- **High Efficiency:** Up to 87% efficiency with synchronous rectification.  
- **1MHz Switching Frequency:** Enables small external components.  
- **Integrated Power MOSFET:** Reduces external component count.  
- **Protection Features:** Includes overcurrent and thermal shutdown.  
- **Soft-Start:** Prevents inrush current at startup.  
- **Low Quiescent Current:** Improves battery life in portable devices.  

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

Application Scenarios & Design Considerations
