Description and Introduction

Low IQ, Dual, 2-Phase Synchronous Step-Down Controller The LTC3827EUH is a high-efficiency, dual-phase synchronous step-down DC/DC controller manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Input Voltage Range:** 4.5V to 38V  
- **Output Voltage Range:** 0.6V to 5.5V  
- **Switching Frequency:** 50kHz to 900kHz (adjustable)  
- **Maximum Output Current:** Up to 25A per phase (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
The LTC3827EUH is designed for high-current, high-efficiency applications. It features dual-phase operation, reducing input and output capacitor requirements while improving thermal performance. The controller uses a constant-frequency, current-mode architecture with adjustable switching frequency and phase-locking capability.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input/output ripple and improves efficiency.  
- **Adjustable Frequency:** 50kHz to 900kHz with external resistor.  
- **Phase-Lockable:** Synchronizable to an external clock.  
- **Precision Reference:** 0.6V ±1% over temperature.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Current Mode Control:** Ensures fast transient response.  
- **Power Good Output:** Monitors output voltage status.  
- **Low Shutdown Current:** <1µA.  
- **Wide Input Range:** Suitable for automotive and industrial applications.  

This controller is commonly used in power supplies for telecom, industrial, and computing systems requiring high efficiency and precise voltage regulation.

- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**
- The LTC3827EUH is designed for high-efficiency, dual-output step-down DC/DC conversion.  
- It drives all N-channel MOSFETs for synchronous rectification.  
- Features include adjustable frequency, phase-lockable operation, and current-mode control for fast transient response.  
- Suitable for applications requiring high power density and efficiency, such as telecom, industrial, and automotive systems.  

### **Features:**
- **Dual Output Controllers:** Independent control for two outputs.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Phase-Lockable Operation:** Synchronizes to an external clock (75kHz to 850kHz).  
- **Current-Mode Control:** Ensures fast transient response and cycle-by-cycle current limiting.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Low Shutdown Current:** <1µA when disabled.  
- **Wide Input Range:** Supports 4.5V to 36V operation.  
- **Power Good Indicators:** Monitors output voltage status.
