ONSEMI FSCQ1565RTYDTU Power Switch
The FSCQ1565RTYDTU is a 650V integrated power switch designed for 170W offline flyback converters. It features a high-voltage SenseFET and an integrated PWM controller optimized for quasi-resonant converters, which offer lower electromagnetic interference (EMI) and higher efficiency compared to traditional hard-switching methods. This device is ideal for noise-sensitive applications such as consumer electronics, signal processing, and audio equipment. It includes advanced protections like overload, overvoltage, and over-current shutoffs with auto-restart, thermal shutdown, under-voltage lockout, and soft-start functionality. Additional features include burst-mode operation for low standby power, pulse-by-pulse current limiting, and extended quasi-resonant switching, making it suitable for efficient, reliable switch-mode power supplies.
