IR1150S ONE Cycle Control PFC SMD IC
The IR1150S is a power factor correction (PFC) integrated circuit (IC) with one-cycle control (OCC) technology, designed for high-performance AC-to-DC power conversion applications. Available in an SMD package, it is optimized for offline power supplies, including power factor correction stages in universal AC input systems, such as those used in PC power supplies, industrial power systems, lighting ballasts, and telecommunication equipment. The IR1150S features one-cycle control, a unique technology that simplifies the control loop by making it possible to regulate the output voltage using a single switching cycle, ensuring high-speed and precise regulation with minimal complexity. This feature enables the IC to respond faster to transients, improving overall system performance and stability.
Features:-
- Low power consumption
- Compact and Easy Integration
- No line voltage sense required
- User-programmable fixed frequency operation
