The FSCQ1265RTYDTU from On Semiconductor is an integrated offline switcher IC optimized for quasi-resonant converters (QRC). This device is well-suited for noise-sensitive applications like color TVs and audio amplifiers due to the lower EMI and higher efficiency characteristic of QRCs.
Key electrical specifications include a 650V breakdown voltage, a 170W power output, and a 20kHz switching frequency. It operates within a supply voltage range of 9V to 20V and features a 95% duty cycle. The IC incorporates several protection features such as pulse-by-pulse current limiting, overload protection (OLP) with auto-restart, over-voltage protection (OVP) with auto-restart, abnormal over-current protection (AOCP) with latch, and internal thermal shutdown (TSD) with latch.
Designed for ease of use, the FSCQ1265RTYDTU includes an integrated PWM controller and a SENSEFET. It also features built-in soft-start (20 ms), under-voltage lockout (UVLO) with hysteresis, and advanced burst-mode operation for low standby power consumption. The device is packaged in a TO-220F-5L (Forming) package suitable for through-hole mounting.
This Pb-Free and Halide-Free device offers a cost-effective platform for designing quasi-resonant switching flyback converters, reducing component count, size, and weight while increasing efficiency and system reliability.
