    High Speed Current Mode
    Pulse Width Modulators U DESCRIPTIO FEATURES









    ■ ■
    ■ The LT ®1241 series devices are 8-pin, fixed frequency,
    current mode, pulse width modulators. They are improved
    plug compatible versions of the industry standard UC1842
    series. These devices have both improved speed and
    lower quiescent current. The LT1241 series is optimized
    for off-line and DC/DC converter applications. They contain a temperature-compensated reference, high gain error amplifier, current sensing comparator and a high
    current totem pole output stage ideally suited to driving
    power MOSFETs. Start-up current has been reduced to
    less than 250µA. Cross-conduction current spikes in
    the output stage have been eliminated, making 500kHz ...
