Description and Introduction

2.5A POWER SWITCHING REGULATOR The L4960H is a monolithic power switching regulator manufactured by STMicroelectronics. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Adjustable from **5.1V to 40V**  
- **Output Current:** Up to **2.5A** (with proper heat sinking)  
- **Input Voltage Range:** **9V to 46V**  
- **Switching Frequency:** **100 kHz** (fixed)  
- **Efficiency:** Up to **90%**  
- **Operating Junction Temperature:** **-40°C to +150°C**  
- **Package:** **TO-220-7 (Multiwatt-7)**  

### **Descriptions:**
- The L4960H is a **step-down (buck) switching regulator** designed for high-efficiency power conversion.  
- It integrates a **PWM controller, power switch, and protection circuits** into a single chip.  
- Suitable for applications requiring **high current and adjustable output voltage**.  

### **Features:**
- **Built-in current limiting** for overload protection.  
- **Thermal shutdown** to prevent overheating.  
- **Soft-start function** to reduce inrush current.  
- **Adjustable output voltage** via external resistors.  
- **Low standby current** in shutdown mode.  
- **Internal oscillator** with fixed frequency for stable operation.
