- **Duty Cycle Range:** 0% to 100%  

### **Descriptions:**  
The MC33060AD is a fixed-frequency pulse-width modulation (PWM) controller designed for DC-DC converter and power supply applications. It features an internal oscillator, error amplifier, and a high-current totem-pole output stage for driving power MOSFETs or bipolar transistors.  

### **Features:**  
- **Complete PWM Control Circuitry**  
- **On-Chip Error Amplifier**  
- **Adjustable Dead-Time Control**  
- **Internal Soft-Start Function**  
- **Undervoltage Lockout (UVLO)**  
- **Precision 5.1V Reference Output (±1%)**  
- **Synchronizable Oscillator**  
- **Current-Limiting and Shutdown Capability**  

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