AN-6075 describes how to design a compact flyback converter. The converter uses the FSQ500L as a controller and has fixed frequency (130KHz), under-voltage lockout (UVLO) protection, soft-start time tuned by external capacitor, overload protection (OLP), leading-edge blanking (LEB), optimized gate turn-on/turn-off driver, thermal shutdown (TSD) protection with hysteresis, and temperature-compensated precision-current sources for loop compensation. The no-load power consumption can be less than 250mW (without auxiliary bias winding) or 60mW (with auxiliary bias winding) for universal AC input voltage range to meet the power conservation requirements. Compared to a linear power supply, the converter has a smaller size and weight, higher efficiency, higher productivity, and higher system reliability.
