### **Descriptions:**
The IR1150S is a single-cycle control (SCC) PFC IC designed for high-efficiency power factor correction in AC-DC power supplies. It uses a patented control method to achieve near-unity power factor with minimal external components. The IC is optimized for continuous conduction mode (CCM) operation and provides robust performance in various power supply applications.

### **Features:**
- **Single-Cycle Control (SCC) Technology:** Enables fast transient response and high power factor.  
- **Built-in Overvoltage Protection (OVP):** Protects against output overvoltage conditions.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Low Standby Power Consumption:** Improves efficiency in light-load conditions.  
- **Internal Startup Timer:** Ensures safe startup operation.  
- **Cycle-by-Cycle Current Limiting:** Enhances system reliability.  
- **Low THD (Total Harmonic Distortion):** Complies with power quality standards.
