Description and Introduction

One Cycle Control PFC IC designed to operate in continuous conduction mode (CCM), designed and qualified for the Industrial market. The IR1150IS is a power factor correction (PFC) controller IC manufactured by Infineon Technologies. Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Infineon Technologies  

### **Specifications:**  
- **Input Voltage Range:** 85 VAC to 265 VAC (universal input)  
- **Operating Frequency:** Up to 250 kHz  
- **Control Method:** Critical Conduction Mode (CrM)  
- **Output Voltage Regulation:** Adjustable  
- **Maximum Duty Cycle:** 95%  
- **Start-Up Current:** < 50 µA  
- **Supply Voltage (VCC):** 10.5 V to 21 V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SOIC-8  

### **Descriptions:**  
The IR1150IS is a high-performance PFC controller designed for power supplies requiring power factor correction. It operates in Critical Conduction Mode (CrM) to improve efficiency and reduce switching losses. The IC integrates protection features such as overvoltage protection (OVP) and undervoltage lockout (UVLO).  

### **Features:**  
- **Single-Stage PFC Control:** Simplifies design for power factor correction.  
- **Low Start-Up Current:** Enables efficient power-up.  
- **Internal Start-Up Timer:** Reduces external component count.  
- **Zero Current Detection (ZCD):** Ensures CrM operation.  
- **Overvoltage Protection (OVP):** Safeguards against output voltage spikes.  
- **Undervoltage Lockout (UVLO):** Prevents operation at low supply voltages.  
- **Lead-Free and RoHS Compliant:** Meets environmental standards.  

This information is based on the manufacturer's datasheet and technical documentation.
