Description and Introduction

DC-DC CONVERTER CONTROL CIRCUITS The MC34063ECN is a monolithic control circuit manufactured by STMicroelectronics (STM). It contains the primary functions required for DC-DC converters and is designed for step-down, step-up, and voltage-inverting applications with minimal external components.

### **Specifications:**
- **Input Voltage Range:** 3V to 40V  
- **Output Switching Current:** Up to 1.5A  
- **Frequency Range:** 100Hz to 100kHz (adjustable with external components)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Duty Cycle Adjustable:** Up to 100%  
- **Package:** PDIP-8 (Plastic Dual In-line Package)  

### **Features:**
- **Low Standby Current**  
- **Short-Circuit Current Limiting**  
- **Internal Temperature Protection**  
- **Adjustable Output Voltage**  
- **Efficient for Buck, Boost, and Inverting Topologies**  

### **Applications:**
- DC-DC converters  
- Voltage regulators  
- Power supply circuits  
- Battery chargers  

The MC34063ECN is widely used in cost-sensitive applications due to its simplicity and versatility.
