Description and Introduction

Adjustable step-down controller with synchronous rectification The L6730 is a switching regulator controller manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** Up to 500kHz  
- **Control Method:** Voltage mode PWM control  
- **Output Current:** Depends on external MOSFETs (driver capability: 1.5A peak source/sink)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-8  

### **Descriptions:**  
The L6730 is a high-performance PWM controller designed for DC-DC step-down (buck) converter applications. It integrates a voltage-mode control loop with adjustable frequency and provides protection features for robust power supply designs.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4.5V to 36V operation.  
- **Adjustable Output Voltage:** Configured via external feedback resistors.  
- **Voltage-Mode PWM Control:** Ensures stable regulation.  
- **High-Side Driver:** Includes a 1.5A gate driver for external N-MOSFETs.  
- **Adjustable Switching Frequency:** Up to 500kHz for flexible design.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Overcurrent Protection (OCP):** Enhances system reliability.  
- **Thermal Shutdown:** Protects against overheating.  

This information is based solely on the manufacturer's datasheet for the L6730.
