Description and Introduction

High Efficiency, High Voltage 50mA Synchronous Step-Down Converter The LTC3642IDD#PBF is a high-efficiency, synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 60V  
- **Output Voltage Range:** 0.8V to 24V (adjustable via external resistors)  
- **Output Current:** Up to 250mA  
- **Switching Frequency:** 100kHz to 2MHz (programmable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  
- **Synchronous Rectification:** Yes  
- **Quiescent Current:** 30µA (in Burst Mode operation)  
- **Protection Features:** Overcurrent, Overtemperature, and Undervoltage Lockout (UVLO)  

### **Descriptions:**  
The LTC3642IDD#PBF is a compact, high-efficiency step-down converter designed for applications requiring wide input voltage ranges and low power consumption. It features a synchronous architecture for improved efficiency and includes Burst Mode operation for reduced quiescent current in light-load conditions.  

### **Features:**  
- **Wide Input Voltage Range (4V to 60V)**  
- **Adjustable Output Voltage (0.8V to 24V)**  
- **Programmable Switching Frequency (100kHz to 2MHz)**  
- **Synchronous Operation for High Efficiency**  
- **Low Quiescent Current (30µA in Burst Mode)**  
- **Integrated Power MOSFETs**  
- **Protection Features (Overcurrent, Overtemperature, UVLO)**  
- **Small 10-Lead DFN Package**  

This device is suitable for industrial, automotive, and battery-powered applications requiring efficient power conversion.
