Description and Introduction

POWER SWITCHING REGULATORS The MC34166TH is a switching regulator IC manufactured by ON Semiconductor. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Voltage:** Adjustable (via external components)  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 100kHz (fixed)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220-5 (TH)  
- **Regulation Type:** Buck (Step-Down)  

### **Descriptions:**  
The MC34166TH is a monolithic switching regulator designed for step-down (buck) applications. It integrates a high-efficiency PWM controller with a power switch, reducing external component count. It is suitable for automotive, industrial, and consumer applications requiring stable DC voltage conversion.  

### **Features:**  
- **Integrated Power Switch:** Reduces external MOSFET requirements.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Thermal Shutdown:** Protects the IC from overheating.  
- **Current Limiting:** Prevents damage from excessive load currents.  
- **Adjustable Output Voltage:** Configured via external resistors.  
- **Low Standby Current:** Improves efficiency in light-load conditions.
