Description and Introduction

DC-to-DC CONVERTER CONTROL CIRCUITS The MC34063 is a monolithic control circuit from Motorola (MOT.ST) that contains the primary functions required for DC-DC converters.  

### **Specifications:**  
- **Input Voltage Range:** 3V to 40V  
- **Output Current:** Up to 1.5A (switch current)  
- **Switching Frequency:** Up to 100kHz  
- **Duty Cycle Adjustable:** Up to 100%  
- **Low Standby Current:** Typically 2.5mA  
- **Operating Temperature Range:** 0°C to +70°C (commercial), -40°C to +85°C (industrial)  

### **Descriptions:**  
The MC34063 integrates a temperature-compensated reference, comparator, controlled duty cycle oscillator, driver, and high-current output switch. It is designed for step-up (boost), step-down (buck), and voltage-inverting (buck-boost) applications.  

### **Features:**  
- **Versatile:** Can be used in boost, buck, and inverting configurations  
- **Low Cost:** Simple external components required  
- **Short-Circuit Protection:** Built-in current limiting  
- **Adjustable Output Voltage:** Via external resistors  
- **Efficient:** Suitable for battery-powered applications  

This information is based on the manufacturer's datasheet for the MC34063 from MOT.ST (Motorola).
