Power Integrations TOPSwitch®-GX series TOP248Y is an offline flyback converter IC designed for high-efficiency power supply applications. This component features an integrated 700V power MOSFET, enabling operation directly from rectified AC mains voltage without the need for a separate external switch. The TOP248Y supports a switching frequency range of 66kHz to 132kHz, with internal frequency control and a maximum duty cycle of 66.8%. Comprehensive fault protection is integrated, including current limiting, over-temperature, and over-voltage protection, ensuring robust operation. Packaged in a TO-220-7C with formed leads, it is suitable for through-hole mounting. This device is commonly utilized in consumer electronics, industrial control systems, and adapter power supplies.
