Description and Introduction

DC-to-DC Converter Control Circuits The MC34063AMR2 is a DC-DC converter IC manufactured by Motorola (MOTO).  

### **Specifications:**  
- **Input Voltage Range:** 3V to 40V  
- **Output Voltage Range:** Adjustable (1.25V to 40V)  
- **Output Current:** Up to 1.5A (switch current)  
- **Switching Frequency:** Up to 100kHz  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The MC34063AMR2 is a monolithic control circuit containing the primary functions required for DC-DC converters. It can be used in step-up (boost), step-down (buck), and voltage-inverting configurations.  

### **Features:**  
- **Low Standby Current**  
- **Short-Circuit Current Limiting**  
- **Adjustable Output Voltage**  
- **Internal Temperature Compensation**  
- **PWM Control for High Efficiency**  

This information is based solely on the manufacturer's datasheet for the MC34063AMR2.

Application Scenarios & Design Considerations

DC-to-DC Converter Control Circuits

Alternative Part Number

  • MC34063AP1G --: Same MC34063A DC-DC converter core in a DIP-8 package from the current successor of Motorola's semiconductor business; widely available and functionally equivalent.
  • LM2575T-ADJ --: Adjustable step-down switching regulator with comparable input range and current capability; a common drop-in style alternative when layout allows a different pinout.
  • MC33063ADR2G --: Directly related MC33063A series converter in SOIC-8, same function and pinout family, offered by the modern ON Semiconductor line as a practical substitute.
