Description and Introduction

High Power Step-Down Synchronous DC/DC Controllers for Low Voltage Operation The LTC3830ES is a high-efficiency, dual-phase synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Switching Frequency:** 50kHz to 900kHz (programmable)  
- **Maximum Output Current:** Up to 25A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**  
The LTC3830ES is designed for high-current, low-voltage applications, providing precise regulation with minimal external components. It features dual-phase operation, reducing input and output ripple currents while improving thermal performance.  

### **Features:**  
- Dual-phase operation for reduced ripple and improved efficiency  
- Programmable switching frequency (50kHz to 900kHz)  
- Adjustable output voltage (0.8V to 5.5V)  
- Integrated MOSFET drivers  
- Current-mode control for fast transient response  
- Overcurrent and overtemperature protection  
- Soft-start and tracking capability  
- Low quiescent current in shutdown mode  

This regulator is commonly used in telecom, industrial, and computing applications requiring high efficiency and precise voltage regulation.
