    DESCRIPTIO U FEATURES










    ■ ■ The LT®1246/LT1247 are 8-pin, fixed frequency, current
    mode, pulse width modulators. These devices are designed to be improved plug compatible versions of the
    industry standard UC1842 PWM circuit. The LT1246/
    LT1247 are 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 totem pole output stage have been ...
