Description and Introduction

2/3 Phase controller with embedded drivers for Intel VR10, VR11 and AMD 6 bit CPUs The part L6713A is a synchronous step-down controller manufactured by STMicroelectronics. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 7V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Maximum Output Current:** Up to 25A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** QFN 5x5, 32-pin  

### **Description:**  
The L6713A is a high-efficiency synchronous buck controller designed for point-of-load (POL) applications. It drives external N-channel MOSFETs in a synchronous rectified buck topology, providing precise voltage regulation for high-current applications.  

### **Features:**  
- **Adjustable Output Voltage:** Via external resistor divider  
- **Programmable Switching Frequency:** 300kHz to 1MHz  
- **Voltage Mode Control:** With input voltage feed-forward compensation  
- **Power Good Indicator:** Monitors output voltage status  
- **Soft-Start & Soft-Stop:** Prevents inrush current  
- **Overcurrent Protection (OCP):** With hiccup mode  
- **Overvoltage Protection (OVP):** Safeguards the load  
- **Undervoltage Lockout (UVLO):** Prevents operation at low input voltage  
- **Thermal Shutdown:** Protects against overheating  

This information is strictly based on the manufacturer's datasheet for the L6713A.

Application Scenarios & Design Considerations

2/3 Phase controller with embedded drivers for Intel VR10, VR11 and AMD 6 bit CPUs

Alternative Part Number

  • ISL6566CRZ --: Multi-phase PWM buck controller with integrated MOSFET drivers, functionally similar to the L6713A for CPU/VRM power stages; different series and vendor.
  • NCP5386MNR2G --: Multi-phase synchronous buck controller with similar VRM control features and driver integration, suitable as a cross-vendor replacement.
  • ADP3198JCPZ-RL --: Multi-phase buck controller for CPU core power with comparable control architecture; different naming and manufacturer make it easy to distinguish.
  • ISL6312ACRZ --: Multi-phase PWM controller with comparable VRM functionality and similar pinout, widely used as a drop-in alternative in CPU power designs.
