в–  в–  The LTВ®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 250ВµA. Cross-conduction current spikes in the totem pole output stage have been …
