Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - TOP244FN TOP244FN

The TOP244FN is an offline switcher from Quarktwin Technology Ltd. designed for AC to DC conversion using flyback topology. It operates at a switching frequency of 132 kHz, which can be reduced to half for specific applications. The device supports a power range of 16 W to 34 W in various configurations, making it suitable for higher power applications without the need for a heatsink up to 34 W in P/G packages. Key features include integrated soft-start functionality to minimize stress and overshoot, programmable current limit, and line under-voltage and over-voltage protection. The device also incorporates frequency jittering to reduce electromagnetic interference (EMI) and improve overall efficiency. It is capable of regulating output to zero load without requiring dummy loading, which enhances energy efficiency in standby modes. The TOP244FN is designed to simplify system design by integrating critical components, thereby reducing the need for external components and associated costs. Its thermal shutdown feature provides automatic fault recovery, ensuring reliable operation in various conditions. This product is suitable for engineers looking for a compact, efficient solution for power supply applications.
