Description and Introduction

Dual 180 Out-of-Phase PWM Step- Down Controllers with POR The MAX1876EEG is a high-efficiency, 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 (MAXIM)  
- **Part Number:** MAX1876EEG  
- **Package:** 24-pin QSOP (Exposed Pad)  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 300kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX1876EEG is a synchronous step-down (buck) DC-DC converter designed for high-efficiency power conversion.  
- It integrates both high-side and low-side MOSFETs, reducing external component count.  
- The device is optimized for applications requiring high efficiency and compact PCB space.  

### **Features:**
- **Integrated Power MOSFETs:** Reduces external component requirements.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  
- **PWM Control:** Fixed-frequency operation for predictable noise performance.  
- **Soft-Start Function:** Limits inrush current during startup.  
- **Overcurrent and Thermal Protection:** Safeguards against fault conditions.  
- **Low Dropout Operation:** Maintains regulation even when input voltage approaches output voltage.  
- **Enable/Shutdown Control:** Allows power management via an external logic signal.  

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

Description and Introduction

Dual 180 Out-of-Phase PWM Step- Down Controllers with POR The MAX1876EEG is a step-up DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.5V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin QSOP  

### **Descriptions:**  
The MAX1876EEG is a high-efficiency, low-noise, 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 is optimized for low-input-voltage operation, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.7V  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode  
- **Adjustable Output Voltage:** Set via external resistors  
- **Low Quiescent Current:** 20µA (typical) in shutdown mode  
- **Soft-Start Function:** Reduces inrush current  
- **Overcurrent Protection:** Prevents damage during fault conditions  
- **Thermal Shutdown:** Protects the device from overheating  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes or design considerations, refer to the official MAX1876 datasheet.
