Description and Introduction

Triple Charge-Pump TFT LCD DC-DC Converter The MAX1747EUP is a high-efficiency, step-down 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:

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

### **Part Number:**  
MAX1747EUP  

### **Package:**  
20-pin TSSOP (Thin Shrink Small Outline Package)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 30V  
- **Output Current:** Up to 2A  
- **Switching Frequency:** 300kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1747EUP is a synchronous step-down (buck) DC-DC converter designed for high-efficiency power conversion. It integrates high-side and low-side MOSFETs, reducing external component count. The device operates in pulse-width modulation (PWM) mode for stable output regulation.  

### **Features:**  
- **Integrated Power MOSFETs** (High-side and low-side)  
- **Adjustable Output Voltage** (1.25V to 30V)  
- **High Efficiency** (up to 95%)  
- **Internal Soft-Start** for controlled startup  
- **Overcurrent Protection** (OCP)  
- **Thermal Shutdown Protection**  
- **Low Dropout Operation** (100% duty cycle capable)  
- **Fixed 300kHz Switching Frequency**  
- **Wide Input Voltage Range (4.5V to 30V)**
