Description and Introduction

Dual 180° Out-of-Phase PWM Step-Down Controller with Power Sequencing and POR The MAX1858EEG+ is a high-efficiency, step-down DC-DC converter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated  

### **Part Number:**  
MAX1858EEG+  

### **Description:**  
The MAX1858EEG+ is a synchronous step-down DC-DC converter designed for high-efficiency power conversion. It operates with input voltages ranging from 2.6V to 5.5V and delivers output currents up to 2A. The device integrates synchronous rectification to improve efficiency and reduce external component count.  

### **Key Features:**  
- **Input Voltage Range:** 2.6V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 2A  
- **High Efficiency:** Up to 95%  
- **Switching Frequency:** 1MHz (fixed)  
- **Integrated Synchronous Rectifier:** Reduces external components  
- **Low Dropout Operation:** 100% duty cycle for low input-output differentials  
- **Power-Saving Mode (Skip Mode):** Improves efficiency at light loads  
- **Soft-Start:** Reduces inrush current  
- **Thermal Shutdown:** Protects against overheating  
- **Package:** 24-Pin QSOP (Exposed Pad)  

### **Applications:**  
- Portable devices  
- Battery-powered equipment  
- Point-of-load regulation  
- Distributed power systems  

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