Description and Introduction

High Power Step-Down Synchronous DC/DC Controllers for Low Voltage Operation The LTC3830ES8 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:** 8-Lead SOIC (ES8)  

### **Descriptions:**  
- The LTC3830ES8 is designed for high-current, low-voltage applications.  
- It features dual-phase operation for improved thermal performance and reduced input/output ripple.  
- Includes adjustable current limit, soft-start, and tracking capabilities.  
- Operates in either forced continuous or pulse-skipping mode for efficiency optimization.  

### **Features:**  
- Dual-phase operation for reduced input/output capacitance requirements  
- Programmable switching frequency (50kHz to 900kHz)  
- Adjustable current limit  
- Differential remote sensing for accurate output regulation  
- Power good output signal  
- Low shutdown current (<1µA)  
- Phase-lockable frequency (PLL) for noise-sensitive applications  

This information is based solely on the manufacturer's datasheet.
