One Cycle Control PFC IC designed to operate in continuous conduction mode (CCM), designed and qualified for the Consumer market **Manufacturer:** International Rectifier (IR)  
**Part Number:** IR1150STRPBF  

### **Specifications:**  
- **Type:** PFC (Power Factor Correction) Controller IC  
- **Topology:** Critical Conduction Mode (CrM)  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Voltage Range:** Adjustable (typically used for boost PFC applications)  
- **Switching Frequency:** Up to 300 kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The IR1150STRPBF is a high-performance, single-stage PFC controller designed for CrM boost converters. It integrates a multiplier, error amplifier, and zero-current detection (ZCD) for efficient power factor correction.  

### **Features:**  
- **Single-Stage PFC:** Simplifies design with integrated control functions.  
- **Critical Conduction Mode:** Ensures high efficiency and low EMI.  
- **Internal Start-Up Timer:** Reduces external component count.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Low Standby Power Consumption:** Improves energy efficiency.
