Description and Introduction

Voltage mode PWM controller with bootstrap anti-discharging system Here are the factual details about part **L6725** from the manufacturer **STMicroelectronics (ST)**:

### **Specifications:**
- **Type:** Synchronous Buck Controller  
- **Input Voltage Range:** 4.5V to 18V  
- **Output Voltage Range:** Adjustable down to 0.6V  
- **Switching Frequency:** Adjustable from 200kHz to 1MHz  
- **Maximum Output Current:** Supports high current with external MOSFETs  
- **Efficiency:** High efficiency due to synchronous rectification  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** Typically available in **HTSSOP-20**  

### **Descriptions:**
- The **L6725** is a synchronous buck controller designed for high-performance DC-DC conversion.  
- It supports adjustable output voltage and switching frequency, making it suitable for various power supply applications.  
- The controller operates with external N-channel MOSFETs, allowing flexibility in power stage design.  
- It includes features like soft-start, overcurrent protection (OCP), and thermal shutdown for reliable operation.  

### **Features:**
- **Adjustable Output Voltage:** Set via external resistor divider.  
- **Programmable Switching Frequency:** Configurable between 200kHz and 1MHz.  
- **Synchronous Rectification:** Improves efficiency by reducing power losses.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Safeguards the circuit from excessive current.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Power Good (PG) Indicator:** Monitors output voltage status.  
- **Low Quiescent Current:** Enhances efficiency in light-load conditions.  

For exact electrical characteristics and application details, refer to the official **STMicroelectronics datasheet** for the **L6725**.
