Description and Introduction

3V to 28V Input, Low-Cost, Hysteretic Synchronous Step-Down Controllers The MAX8578EUB+T is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX8578EUB+T  
- **Package:** 10-µMAX® (3mm x 5mm)  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Output Current:** Up to 600mA (depending on input voltage)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:** Low startup voltage (0.7V), internal synchronous rectifier, low quiescent current (25µA typical), and thermal shutdown protection.  

### **Descriptions:**  
The MAX8578EUB+T is a high-efficiency, step-up DC-DC converter designed for battery-powered applications. It integrates a synchronous rectifier to improve efficiency and reduce external component count. The device operates from input voltages as low as 0.7V, making it suitable for single-cell alkaline or NiMH battery applications.  

### **Features:**  
- **Wide Input Voltage Range:** 0.7V to 5.5V  
- **Adjustable Output Voltage:** 1.8V to 5.5V  
- **High Efficiency:** Up to 95%  
- **Low Quiescent Current:** 25µA (typical)  
- **Internal Synchronous Rectifier:** Eliminates external Schottky diode  
- **1.2MHz Fixed Switching Frequency:** Reduces inductor size  
- **Low Startup Voltage:** 0.7V  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Small Package:** 10-µMAX (3mm x 5mm)
