    AS3842 family of control ICs provide pin-for-pin replacement of the
    industry standard UC3842 series of devices. The devices are
    redesigned to provide significantly improved tolerances in power sup-
    ply manufacturing. The 2.5 V reference has been trimmed to 1.0%
    tolerance. The oscillator discharge current is trimmed to provide guar-
    anteed duty cycle clamping rather than specified discharge current.
    The circuit is more completely specified to guarantee all parameters
    impacting power supply manufacturing tolerances.
