Description and Introduction

POWER SWITCHING REGULATORS The MC34167TH is a switching regulator IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** High (typically >85%)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (TH = Through-Hole)  

### **Descriptions:**  
- The MC34167TH is a monolithic switching regulator with an integrated power switch.  
- It is designed for step-down (buck), step-up (boost), and inverting applications.  
- Features include current limiting, thermal shutdown, and under-voltage lockout (UVLO).  

### **Features:**  
- **Integrated Power Switch:** Simplifies design and reduces external components.  
- **Adjustable Output Voltage:** Configured using external resistors.  
- **Current Limiting:** Protects the device from overcurrent conditions.  
- **Thermal Shutdown:** Prevents damage due to excessive temperature.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Low Standby Current:** Improves efficiency in light-load conditions.  

This IC is commonly used in power supply designs for industrial, automotive, and consumer electronics applications.
