Description and Introduction

Low IQ, Dual, 2-Phase Synchronous Step-Down Controller The LTC3827IG-1#PBF is a high-efficiency, dual monolithic synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** 0.8V to 24V (adjustable)  
- **Switching Frequency:** 50kHz to 900kHz (programmable)  
- **Maximum Output Current:** Up to 20A per phase (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**  
- The LTC3827IG-1#PBF is designed for high-power applications requiring precise voltage regulation.  
- It features two independent controllers, allowing for dual-output or multiphase operation.  
- The device includes adaptive gate drive timing to optimize efficiency.  
- It supports forced continuous, pulse-skipping, or Burst Mode® operation for improved light-load efficiency.  

### **Features:**  
- **Dual Output or Multiphase Operation:** Can be configured for two independent outputs or a single high-current output.  
- **Programmable Frequency:** Allows optimization for efficiency or component size.  
- **Precision Reference:** ±1% voltage accuracy over temperature.  
- **Current Mode Control:** Ensures fast transient response and stable operation.  
- **Synchronizable:** Can be synchronized to an external clock.  
- **Short-Circuit Protection:** Includes foldback current limiting.  
- **Soft-Start:** Adjustable soft-start for controlled startup.  
- **Burst Mode Operation:** Enhances light-load efficiency.  

This device is commonly used in telecom, industrial, and automotive applications where high efficiency and precise voltage regulation are required.
