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.

The FAN7171_F085 is a monolithic high-side gate drive IC, which can drive high-speed MOSFETs and IGBTs that operate up to +600V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The UVLO circuit prevents malfunction when VBS is lower than the specified threshold voltage. The high-current and low-output voltage drop feature makes this device suitable for sustained switch driver and energy recovery switch driver in the Plasma Display Panel application, motor drive inverter.
