Description and Introduction

WCDMA Cellular Phone 600mA Buck Regulators The MAX1820XEBC is a 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  
- **Type:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 5-pin μMAX (UCSP)  

### **Descriptions:**  
The MAX1820XEBC is a high-efficiency, step-up DC-DC converter designed for low-voltage applications. It is optimized for battery-powered devices where minimal input voltage and high efficiency are critical. The device integrates a power switch and can operate from input voltages as low as 0.7V, making it suitable for single-cell alkaline or NiMH/NiCd battery systems.  

### **Features:**  
- Ultra-low input voltage operation (0.7V min)  
- Adjustable output voltage (up to 5.5V)  
- Internal 0.5Ω power MOSFET switch  
- Low quiescent current (50μA typical)  
- Soft-start feature to limit inrush current  
- Overcurrent and thermal shutdown protection  
- Compact μMAX package for space-constrained applications  

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