Description and Introduction

1.5A, 3MHz Synchronous Step-Up DC/DC Converter with Output Disconnect The LTC3422EDD#PBF is a high-efficiency, synchronous step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 0.5V to 5V  
- **Output Voltage Range:** Up to 5.25V  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1MHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions:**  
The LTC3422EDD#PBF is designed for low-input-voltage applications, such as single-cell or dual-cell alkaline/NiMH battery-powered devices. It features a synchronous rectifier for high efficiency and includes an internal soft-start to limit inrush current.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 0.5V to 5V.  
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Low Quiescent Current:** 20µA in shutdown mode.  
- **Internal Soft-Start:** Prevents excessive inrush current.  
- **Fixed Frequency Operation:** 1MHz switching frequency minimizes external component size.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Small Footprint:** 10-lead DFN package for space-constrained applications.  

This device is commonly used in portable electronics, energy harvesting, and battery-powered systems requiring efficient step-up conversion.
