Description and Introduction

WCDMA Cellular Phone 600mA Buck Regulators The MAX1820XEBC+T 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  
- **Part Number:** MAX1820XEBC+T  
- **Type:** Step-Down DC-DC Converter (Buck Converter)  
- **Input Voltage Range:** 2.6V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to VIN  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 5-Pin μMAX (SOT23-5)  

### **Descriptions:**
The MAX1820XEBC+T is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates a synchronous rectifier to minimize external component count and improve efficiency. The device operates at a fixed 1MHz switching frequency, allowing the use of small inductors and capacitors. It features a low-dropout (LDO) mode for improved efficiency at light loads.

### **Features:**
- **High Efficiency (up to 95%)**  
- **Synchronous Rectification**  
- **Low Quiescent Current (40μA typical)**  
- **Adjustable Output Voltage (0.8V to VIN)**  
- **1MHz Fixed Switching Frequency**  
- **Internal Soft-Start**  
- **Overcurrent and Thermal Protection**  
- **Small 5-Pin μMAX Package**
