Description and Introduction

UPFC ONE CYCLE CONTROL PFC IC The IR1150ISTR is a PFC (Power Factor Correction) controller IC manufactured by Infineon Technologies. Below are the factual specifications, descriptions, and features from the manufacturer's knowledge base:

### **Specifications:**
- **Manufacturer:** Infineon Technologies  
- **Part Number:** IR1150ISTR  
- **Type:** Single-Phase PFC Controller IC  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 10V to 20V  
- **Maximum Switching Frequency:** 200 kHz  
- **Control Method:** One-Cycle Control (OCC)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Drive Current:** ±1.5A (peak)  

### **Descriptions:**
- The IR1150ISTR is a high-performance, single-stage PFC controller designed for continuous conduction mode (CCM) operation.  
- It uses One-Cycle Control (OCC) to achieve near-unity power factor with minimal external components.  
- Suitable for AC-DC power supplies, LED drivers, and industrial power applications.  

### **Features:**
- **One-Cycle Control (OCC):** Simplifies feedback loop design and improves transient response.  
- **High Power Factor (>0.99):** Ensures compliance with energy efficiency standards.  
- **Low THD (Total Harmonic Distortion):** Reduces input current distortion.  
- **Integrated Overvoltage Protection (OVP):** Safeguards against output overvoltage conditions.  
- **Cycle-by-Cycle Current Limiting:** Enhances system reliability.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Standby Power Consumption:** Improves efficiency in light-load conditions.  

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