Description and Introduction

PLASTIC ENCAPSULATED DEVICES The MAX8556ETE is a step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX8556ETE  
- **Package:** 16-TQFN (3x3)  
- **Input Voltage Range:** 2.6V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.6V to VIN  
- **Output Current:** Up to 6A  
- **Switching Frequency:** 500kHz to 2MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX8556ETE is a high-efficiency, synchronous step-down DC-DC converter designed for applications requiring high output current in a compact footprint. It integrates low RDS(ON) MOSFETs to minimize power dissipation and supports a wide input voltage range, making it suitable for point-of-load (POL) regulation in portable and embedded systems.

### **Features:**  
- **Integrated Power MOSFETs** (Low-side and high-side)  
- **Adjustable Output Voltage** (0.6V to VIN)  
- **Programmable Switching Frequency** (500kHz to 2MHz)  
- **Low Dropout Operation** (100% duty cycle)  
- **Power-Good Output Monitor**  
- **Soft-Start Function**  
- **Overcurrent and Thermal Protection**  
- **Synchronizable to External Clock**  
- **Compact 16-TQFN Package**
