Description and Introduction

HALL EFFECT PICKUP IGNITION CONTROLLER The L497 is a switching regulator IC manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 15V to 50V  
- **Output Voltage Range:** 5.1V to 40V (adjustable via external resistors)  
- **Output Current:** Up to 10A (with proper heat sinking)  
- **Switching Frequency:** 200 kHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** Multiwatt-15 (through-hole)  

### **Descriptions:**
- The L497 is a monolithic step-down (buck) switching regulator designed for high-efficiency DC-DC conversion.  
- It includes a built-in power MOSFET, PWM controller, and protection features.  
- Suitable for applications requiring high current and voltage regulation, such as power supplies, industrial systems, and automotive electronics.  

### **Features:**
- **Integrated Power MOSFET:** Reduces external component count.  
- **PWM Control:** Fixed-frequency operation for stable performance.  
- **Protection Circuits:** Includes overcurrent, thermal shutdown, and undervoltage lockout (UVLO).  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **High Efficiency:** Minimizes power dissipation.
