Power Integrations TOPSwitch® TOP103YAI is an offline switcher IC designed for a wide range of power conversion applications. This component supports Boost, Buck, Flyback, and Forward topologies, offering design flexibility. It features an integrated switch with a breakdown voltage of 350V and a switching frequency of 100kHz. The device is packaged in a TO-220-3 through-hole configuration, facilitating straightforward board mounting. With a maximum power output of 90W and fault protection including current limiting and over-temperature shutdown, the TOP103YAI ensures robust operation. Its isolated output and ability to operate across an extended temperature range from -40°C to 150°C make it suitable for industrial, consumer electronics, and appliance applications where reliable offline power conversion is critical. The 67% duty cycle further enhances its efficiency in various power supply designs.
