They are ideal for high frequency and high pulse risetime circuits and find wide application in snubbers, switcher and high voltage power suppliers and electronics lighting ballasts.
也大量应用于缓冲器，转换器，高电压的电源和电子镇流器上面。

The low voltage burden (V1) and corresponding fast risetime are achieved by the high gain op amp, which forces V1 to be nearly zero.
