Description and Introduction

3-Phase, Buck Controllers for AMD CPUs The LTC3733CG is a synchronous buck switching regulator controller manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features:

### **Manufacturer:**  
- Linear Technology (LT) / Analog Devices  

### **Part Number:**  
- LTC3733CG  

### **Description:**  
- The LTC3733CG is a high-performance, dual-phase synchronous buck switching regulator controller designed for high-current applications. It drives external N-channel MOSFETs to efficiently step down higher input voltages to lower output voltages.  

### **Key Features:**  
1. **Dual-Phase Operation:**  
   - Reduces input and output ripple current, improving efficiency and thermal performance.  

2. **Wide Input Voltage Range:**  
   - Operates from **4.5V to 36V**, suitable for a variety of power supply applications.  

3. **Adjustable Output Voltage:**  
   - Output can be set from **0.8V to 5.5V** using an external resistor divider.  

4. **High Switching Frequency:**  
   - Programmable frequency up to **550kHz** per phase.  

5. **Precision Reference:**  
   - **0.8V ±1%** reference voltage for accurate regulation.  

6. **Current Mode Control:**  
   - Ensures fast transient response and stable operation.  

7. **Power Good Indicator:**  
   - Monitors output voltage status.  

8. **Soft-Start & Tracking:**  
   - Adjustable soft-start and tracking capability for controlled power-up sequencing.  

9. **Overcurrent & Overtemperature Protection:**  
   - Includes foldback current limiting and thermal shutdown.  

10. **Package:**  
    - **28-Lead SSOP (CG Package)**  

### **Applications:**  
- High-current DC/DC converters  
- Distributed power systems  
- Servers, telecom, and networking equipment  
- Industrial and automotive power supplies  

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

Description and Introduction

3-Phase, Buck Controllers for AMD CPUs The LTC3733CG is a synchronous step-down switching regulator controller manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** 0.8V to 5.5V (adjustable)  
- **Switching Frequency:** 50kHz to 600kHz (programmable)  
- **Maximum Output Current:** Up to 20A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**  
- The LTC3733CG is a high-performance, dual-phase synchronous buck controller designed for high-current applications.  
- It uses a constant-frequency current-mode architecture for precise regulation and fast transient response.  
- The device supports multi-phase operation (up to 12 phases with external clock synchronization) for high-power applications.  
- It includes adaptive voltage positioning (AVP) to improve transient performance.  

### **Features:**  
- **Dual-Phase Operation:** Reduces input and output ripple current.  
- **Programmable Frequency:** Adjustable from 50kHz to 600kHz.  
- **Current-Mode Control:** Ensures cycle-by-cycle current limiting.  
- **Power Good Output:** Monitors output voltage status.  
- **External Synchronization:** Allows phase-locking to an external clock.  
- **Soft-Start:** Adjustable for controlled startup.  
- **Low Dropout Operation:** Maximizes efficiency at low output voltages.  
- **Thermal Protection:** Prevents overheating.
