Power Integrations TOPSwitch® TOP103YN is an offline switching regulator IC designed for high-performance power supply applications. This component integrates a high-voltage MOSFET and control circuitry into a single TO-220-3 package, simplifying board design and reducing component count. The TOP103YN supports multiple topologies including Boost, Buck, Flyback, and Forward configurations, operating at a switching frequency of 100kHz. It offers a maximum output power of 90W and features robust fault protection mechanisms such as current limiting and over-temperature protection. Its isolated output design is suitable for a wide range of applications, including consumer electronics, industrial controls, and appliance power supplies, where reliable and efficient offline power conversion is critical. The device operates across an extended temperature range of -40°C to 150°C (TJ).
