Description and Introduction

1.5A, Step-Up/Down/Inverting Switching Regulator The MC33063ADR2 is a monolithic control circuit manufactured by ON Semiconductor. It is designed for DC-DC converter applications and includes the primary functions required for step-up, step-down, and voltage-inverting configurations.  

### **Specifications:**  
- **Input Voltage Range:** 3V to 40V  
- **Output Switch Current:** 1.5A (peak)  
- **Oscillator Frequency:** 100kHz (fixed)  
- **Duty Cycle Adjustable:** Up to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The MC33063ADR2 integrates a temperature-compensated reference, comparator, controlled duty-cycle oscillator, driver, and high-current output switch. It is optimized for efficient power conversion in battery-powered systems, portable devices, and automotive applications.  

### **Features:**  
- **Wide Input Voltage Range** (3V to 40V)  
- **Low Standby Current**  
- **Short-Circuit Current Limiting**  
- **Adjustable Output Voltage**  
- **Efficiency Up to 90%**  
- **Internal Current Limiting and Thermal Shutdown**  

This device is commonly used in power supply designs requiring step-up (boost), step-down (buck), or voltage-inverting (buck-boost) conversion.
