Product Summary

The SG6961SZ is an 8-pin boundary mode PFC controller IC intended for controlling PFC pre-regulators. The SG6961SZ provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable to ensure safe operation during AC brownouts. An innovative multi-vector error amplifier is built in to provide rapid transient response and precise output voltage clamping. The applications of the SG6961SZ include Electric Lamp Ballasts, AC-DC Switching Mode Power Converter, Open-Frame Power Supplies and Power Adapters, Flyback Power Converters with ZCS/ZVS.
