Categories: AC DC Converters, Offline Switches
Quality Control: Learn More
The onsemi FSQ321 is an 8-DIP offline flyback converter from the FPS™ series. This component features an integrated 650V switch and operates within a 55kHz to 67kHz switching frequency range. Designed for isolated power supplies, it supports a maximum output power of 12W. Key fault protection mechanisms include current limiting, overload, over-temperature, and over-voltage protection, ensuring robust operation. The device requires a Vcc/Vdd supply voltage between 8V and 20V, with a typical start-up voltage of 12V. Mounting is facilitated via through-hole technology. Applications for this highly integrated solution span consumer electronics, industrial power supplies, and lighting control systems.
